| As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco NX-OS engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-76456 are related to improper input validation of special elements used in a command issue that are grouped under the Common Weakness Enumeration (CWE) CWE-20. |
| A vulnerability in the web-based user interface of Cisco License On-Prem, formerly Cisco Smart Software Manager On-Prem (SSM On-Prem), could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system.
This vulnerability is due to improper validation of user-supplied content within configurations that are submitted to the web-based management interface. An attacker could exploit this vulnerability by updating configurations within the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges.
To exploit this vulnerability, the attacker must have valid administrative credentials. Because only an attacker who already holds system administrator privileges can exploit the vulnerability, the only additional privileges gained include the ability to turn off the system, which an administrative user could not normally do. |
| Path traversal vulnerability in the Satel Iberia SenNet Datalogger Serie 200, specifically in the web portal provided by the device, which allows an authenticated user to read any file or list any directory accessible to the system user running the web server. This is possible by modifying the URL to include a path traversal payload. Successful exploitation of this vulnerability could allow an attacker to access critical system files containing confidential information. |
| In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_cut_tail() in libntfs-3g/index.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by creating a file in a specially crafted directory. |
| wger is a free, open-source workout and fitness manager. Prior to version 2.6, an authenticated attacker can inject arbitrary workout log entries into any other user's `SlotEntry` by supplying the victim's `slot_entry` ID in a `POST /api/v2/workoutlog/` request. The `slot_entry` foreign key is not included in the ownership verification performed by `WorkoutLogViewSet.get_owner_objects()`, so the server accepts and persists the cross-user reference without error. Because `SlotEntry.get_config_data()` retrieves associated logs via `self.workoutlog_set.all()` with no user filter, the attacker's injected data is silently folded into the victim's progressive-overload calculations, corrupting their auto-generated weight and repetition targets. Version 2.6 contains a patch. |
| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. False positive. |
| A vulnerability in the endpoint group (EPG) contract functionality of Cisco Nexus 9000 Series Fabric Switches in ACI Mode could allow an unauthenticated, remote attacker to bypass configured EPG contracts.
This vulnerability is due to an improper control with EPG contracts. An attacker could exploit this vulnerability by sending IPv4 or IPv6 packets using UDP source and destination ports that are assigned to DHCP traffic through an affected device. A successful exploit could allow the attacker to bypass EPG contracts on the affected device. |
| A security vulnerability has been identified in FlexNet Publisher lmadmin. The vulnerability exists in a SOAP handler, where a hardcoded authentication bypass could allow an unauthenticated user to obtain a privileged administrator session without providing valid credentials. |
| A predictable seed in the pseudo-random number generator (PRNG) in the IFTTT pairing token generation of the ASUS RT-BE57 router allows an unauthenticated nearby user to derive the pairing token and read or modify router settings via observed values from an administrator-initiated IFTTT pairing session.Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information. |
| A stack-based buffer overflow in the ASUS router modules allows an authenticated nearby user to execute arbitrary code via a crafted configuration file upload that exceeds the expected buffer size.Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information. |
| ieee802154_decipher_data_frame() in subsys/net/l2/ieee802154/ieee802154_frame.c computed payload_len = net_pkt_get_len(pkt) - ll_hdr_len - authtag_len without first checking that the received frame is at least ll_hdr_len + authtag_len bytes long. All three variables are uint8_t, so a frame whose payload is shorter than the configured authentication tag makes the subtraction wrap around to a large value (up to 255).
The wrapped length is passed unchanged to ieee802154_decrypt_auth() and on to the CCM operation as cipher_pkt.in_len/out_buf_max, with apkt->tag pointing at frame + ll_hdr_len + payload_len. Because the receive buffer is allocated to the exact length of the frame received from the radio driver, the crypto layer then reads several hundred bytes past the end of the packet buffer and writes the same number of decrypted bytes back over it in place. The frame's authentication tag is only verified after this processing has taken place, so no key material, association or prior authentication is needed — a single crafted short frame from any device in radio range is sufficient. Frame validation in ieee802154_validate_frame() does not prevent it: a data frame is accepted with a one-byte payload.
The result is an out-of-bounds read and an out-of-bounds write of up to roughly 240 bytes into the adjacent network-buffer pool, corrupting other packets or allocator metadata and typically faulting the target. The out-of-bounds content is not attacker-chosen (it is ciphertext XOR keystream over out-of-bounds memory) and the frame is dropped when tag verification fails, so the primary impact is memory corruption and denial of service rather than information disclosure.
Exposure is limited to configurations that enable the experimental CONFIG_NET_L2_IEEE802154_SECURITY option, select a crypto device via CONFIG_NET_L2_IEEE802154_SECURITY_CRYPTO_DEV_NAME, and have established a security session with a level other than IEEE802154_SECURITY_LEVEL_NONE; with security disabled or at level NONE the tag length is zero and no underflow occurs. The fix rejects frames shorter than ll_hdr_len + authtag_len before the subtraction, and adds the matching guard on the transmit side in ieee802154_create_data_frame(). |
| Insertion of Sensitive Information into Log File in certain ASUS router models allows a remote authenticated attacker to obtain DDNS credentials from the system log, potentially enabling modification of DNS settings.Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information. |
| Improper Neutralization of Input During Web Page Generation (“Cross-site Scripting”) in ASUS router modules allows a remote attacker to read DOM information, modify router settings, and cause a denial-of-service condition when an authenticated user visits a crafted URL.Refer to the '
Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information. |
| Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.1 to 2.11.0, ANCHORARRAY recursively calls the exported CalcCellValue function, creating a fresh calculation context at each cycle and bypassing in-flight and iteration controls. ANCHORARRAY calls CalcCellValue instead of cellResolver, so each recursive hop receives a new calcContext and loses cycle state. When mutually referencing dynamic-array formulas are evaluated directly or through formula-evaluating APIs, each recursion hop resets the cycle budget and prevents completion-based caches from breaking the cycle, allowing an attacker to cause a fatal Go stack overflow and abort the process. No fixed version is available as of this review. |
| This vulnerability exists in the ERP system due to unsafe deserialization of user controlled data in the affected functionality. An unauthenticated remote attacker could exploit this vulnerability by supplying specially crafted data to the vulnerable functionality of the targeted system.
Successful exploitation of this vulnerability could allow the attacker to execute arbitrary code, manipulate application data or perform other unintended actions on the targeted system. |
| This vulnerability exists in the ERP system due to insufficient validation and parameterization of user supplied input in an API endpoint. An unauthenticated remote attacker could exploit this vulnerability by supplying specially crafted input to the vulnerable endpoint.
Successful exploitation of this vulnerability could allow the attacker to perform SQL injection attacks on the targeted system. |
| This vulnerability exists in the ERP system due to improper validation of payment callback parameters and inadequate authentication controls in API endpoint. An unauthenticated remote attacker could exploit this vulnerability by manipulating the parameter to cause the application to establish an authenticated session for an arbitrary user without valid payment verification.
Successful exploitation of this vulnerability could allow the attacker to bypass authentication and gain unauthorized access to other user accounts on the targeted system. |
| Backstage is an open framework for building developer portals. Prior to 1.14.6, the @backstage/plugin-techdocs-node package is affected by improper validation of mkdocs theme configuration in techdocs. When TechDocs is configured to build documentation locally or in a container, a user with write access to a registered repository can include configuration values in mkdocs.yml that cause arbitrary code execution during the documentation build process. This issue is fixed in versions 1.14.6 and 1.15.4. |
| Backstage is an open framework for building developer portals. Prior to 1.54.6, cloud storage catalog providers did not sufficiently validate object paths. A principal able to create or rename objects in a configured Azure Blob Storage or AWS S3 catalog source could cause catalog descriptors to be read from outside the intended storage boundary, limited to locations reachable with the backend's configured credentials. This issue is fixed in 1.54.6. |
| Backstage is an open framework for building developer portals. Prior to 0.4.20, the @backstage/plugin-auth-backend-module-oidc-provider package is affected by improper authentication in the oidc provider. Deployments using OIDC email-based identity resolution with a provider that permits unverified email addresses may allow an authenticated provider user to assume another catalog identity. This may grant access and permissions associated with that user. No direct availability impact is demonstrated. This issue is fixed in version 0.4.20. |
