| In the Linux kernel, the following vulnerability has been resolved:
ipv6: rpl: fix hdrlen overflow in ipv6_rpl_srh_decompress()
ipv6_rpl_srh_decompress() computes:
outhdr->hdrlen = (((n + 1) * sizeof(struct in6_addr)) >> 3);
hdrlen is __u8. For n >= 127 the result exceeds 255 and silently
truncates. With n=127 (cmpri=15, cmpre=15, pad=0, hdrlen=16):
(128 * 16) >> 3 = 256, truncated to 0 as __u8
The caller in ipv6_rpl_srh_rcv() then places the compressed header
at buf + ((ohdr->hdrlen + 1) << 3). With hdrlen=0 this is buf + 8,
but the decompressed region occupies buf[0..2055] (8-byte header
plus 128 full addresses). The compressed header overlaps the
decompressed data, and ipv6_rpl_srh_compress() writes into this
overlap, corrupting the routing header of the forwarded packet.
The existing guard at exthdrs.c:546 checks (n + 1) > 255, which
prevents n+1 from overflowing unsigned char (the segments_left
field), but does not prevent the computed hdrlen from overflowing
__u8. n=127 passes because 128 <= 255, yet hdrlen=256 does not
fit.
Tighten the bound to (n + 1) > 127. This caps n at 126, giving
hdrlen = (127 * 16) >> 3 = 254, which fits in __u8. The compressed
header then lands at buf + ((254 + 1) << 3) = buf + 2040, exactly
past the decompressed region (buf[0..2039]). No overlap. 127
segments is well beyond any realistic RPL deployment. |
| The Live Composer WordPress plugin before 2.1.24 does not sanitise and escape some of its page-builder module settings before outputting them, allowing users with access to the builder (Administrator by default) to inject arbitrary JavaScript that executes when the affected page is viewed by any visitor; this has impact even on administrators where the unfiltered_html capability is disallowed, e.g. in multisite setups. |
| The AutomatorWP WordPress plugin before 6.0.8 does not bind the requests that complete its Zoom and AWeber integration connections to the administrator who started them, allowing attackers to make a logged-in administrator replace the stored integration credentials with the attacker's own via a CSRF attack, diverting the data the site sends to those services into an account the attacker controls. Exploitation requires the integration to already be connected and knowledge of the site's OAuth client identifier. |
| The Gravity Forms WordPress plugin before 3.2.2 does not properly restrict the file types that unauthenticated users can upload through its chunked file upload feature, allowing them to read server environment variables and the contents of files within the web root on servers configured to parse Server-Side Include documents, such as Apache with SSI enabled. |
| The NotificationX WordPress plugin before 3.3.7 does not perform any capability or nonce check on one of its REST routes, allowing unauthenticated users to update a NotificationX WordPress plugin before 3.3.7 option and to repeatedly trigger emails sent through the site's own mail server. |
| The Schema & Structured Data for WP & AMP WordPress plugin before 1.70 does not verify that a user may edit a post before letting them change that post's structured data settings, allowing users with the Contributor role and above, when an administrator has granted them access to the Schema & Structured Data for WP & AMP WordPress plugin before 1.70, to disable, alter or reset the structured data of posts they do not own. |
| The User Registration & Membership WordPress plugin before 5.3.2 does not verify that a payment has actually been completed before extending a paid membership subscription, allowing authenticated users with an active paid subscription to renew it indefinitely without paying. |
| The AskAny WordPress plugin before 2.2.0 does not validate the extension or content of files attached to chat messages, trusting the browser-supplied file type instead, which allows unauthenticated users to upload PHP files and execute arbitrary code when visitor attachments are enabled. |
| The Photo Engine (Media Organizer & Lightroom) WordPress plugin before 6.6.2 does not check that a user may delete the media in a collection before deleting it along with the collection, allowing users with the Author role and above to permanently delete other users' synced media, including administrators'. |
| The Schema & Structured Data for WP & AMP WordPress plugin before 1.70 does not check that the importing user may edit the posts named in a settings backup, nor restrict the import to its own post types, allowing users whose role an administrator has granted access to the Schema & Structured Data for WP & AMP WordPress plugin before 1.70's settings to modify, re-author, unpublish or trash any post or page on the site and write arbitrary post meta. |
| The Limit Login Attempts Security WordPress plugin before 3.4.2 does not validate the destination of a server-side request built from a user-supplied setup value, allowing users with administrator privileges to make the site issue requests to arbitrary hosts, including internal ones (SSRF). |
| The GetPaid WordPress plugin from 2.8.63 to 2.8.64 does not ensure item quantities on its payment forms are whole numbers, allowing unauthenticated users to have an invoice for a priced item marked as paid without being charged. |
| The Pay with a tweet WordPress plugin through 1.0.5 does not validate a file path before deleting it, nor does it restrict access to the relevant administration screens, allowing users with a role as low as Subscriber to delete arbitrary files on the server, which can lead to a full site compromise. |
| The Elementor Website Builder WordPress plugin before 4.3.6 does not validate or escape an element identifier before rendering it into a client-side framework attribute that is evaluated as JavaScript, allowing users with the Contributor role to store scripts that execute in the browser of anyone viewing the affected content, including an administrator reviewing the submission for publication. |
| The Live Composer WordPress plugin before 2.1.24 does not sanitise and escape some of its module settings before outputting them in an href attribute, which could allow high-privilege users such as administrators to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (e.g. in multisite setups). |
| The Live Composer WordPress plugin before 2.1.24 does not sanitise and escape some of its staff member settings before outputting them in pages, which could allow high-privilege users such as administrators to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (e.g. in multisite setups). |
| The User Registration & Membership WordPress plugin before 5.3.2 does not verify that a discount coupon applied to a paid membership plan is actually valid for that plan before treating a fully discounted order as paid, allowing unauthenticated users to be granted the role mapped to a paid plan without paying for it, which can lead to privilege escalation up to administrator where a plan is mapped to a privileged role. |
| The User Registration & Membership WordPress plugin before 5.3.2 does not enforce its payment-before-login restriction when a registration is submitted without a membership selection, allowing unauthenticated users to create an account on a payment-gated registration form and log in without completing payment. |
| The Download Manager WordPress plugin before 3.3.73, Download Manager WordPress plugin before 7.6.2 does not verify that a visitor is allowed to access a package before its media-preview renderers issue a download key for it, allowing unauthenticated visitors to download password-locked and role-restricted files by reading the key from a public page. |
| The Forminator Forms WordPress plugin before 1.58.4 does not enforce payment on the server side when a form's configured payment gateway is unavailable, allowing unauthenticated visitors to complete a payment-gated User Registration form without paying and be assigned the form's configured role, up to administrator, after the gateway has been connected and later disconnected. |
