| 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 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 Dynific Addons for Elementor (formerly Anywhere Elementor) WordPress plugin before 1.3.1 does not perform a capability or nonce check on an AJAX action that saves its module configuration, allowing any authenticated user, including Subscribers, to enable or disable the Dynific Addons for Elementor (formerly Anywhere Elementor) WordPress plugin before 1.3.1's modules site-wide. |
| The Data Tables Generator by Supsystic WordPress plugin before 1.15.8 does not perform any authorization or ownership check before returning the stored contents of a table, relying only on a nonce that is exposed to every anonymous visitor, allowing unauthenticated users to read the full contents of any table by its identifier, including tables that are never published anywhere on the site. |
| 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 Contest Gallery WordPress plugin before 34.0.3 does not sanitise the name of files uploaded through its e-commerce sale file-replacement feature, allowing authenticated users with Author-level access and above to write files with an arbitrary name and extension to a web-accessible directory and, by overwriting the directory's protection file through the same flow, achieve Remote Code Execution. |
| The Dynific Addons for Elementor (formerly Anywhere Elementor) WordPress plugin before 1.3.1 does not perform a status or capability check when resolving post identifiers passed to one of its shortcodes, allowing authenticated users with at least the Contributor role to disclose the content of other users' draft, private and password-protected posts. An Author can republish that content to anonymous visitors. |
| The NotificationX WordPress plugin before 3.3.7 does not perform any capability, authentication or nonce check on its notification preview path, allowing unauthenticated users to disclose the content of private, draft, pending and password-protected posts and to execute arbitrary registered shortcodes by supplying crafted preview data on any front-end request. |
| The Advanced Product Fields (Product Addons) for WooCommerce WordPress plugin from 1.6.22 to 1.7.3 does not validate that a submitted value for a required paid product option matches one of the configured choices, only that it is not empty, allowing unauthenticated users to add a product to the cart and complete an order while skipping the required option's surcharge and paying only the base product price. |
| The Schema & Structured Data for WP & AMP WordPress plugin before 1.70 does not verify that a post is publicly viewable before returning its approved comments through the review feature, allowing unauthenticated attackers to read approved comments on private, draft and password-protected posts, and to retrieve approved comments site-wide. |
| 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 Live Composer WordPress plugin before 2.1.24 does not escape several attributes of one of its page-builder shortcodes before outputting them inside HTML tag attributes, allowing users with the Contributor role and above to store a payload that executes in the browser of anyone who views the post, including an administrator reviewing the pending submission. |
| The Smush WordPress plugin before 4.3.6 does not verify that a user is authorised to act on the targeted media attachment, only checking a broad upload-files capability, which allows users with the Author role and above to optimise and restore attachments owned by other users, altering their files on disk and consuming the stored backup. |
| 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 Somatic Framework WordPress plugin through 1.8.14 does not perform an authorization check or validate a user-supplied file path before deleting it, allowing any authenticated user, such as a subscriber, to delete arbitrary files on the server, which can lead to a full site takeover. |
| The Download Manager WordPress plugin before 3.3.73, Download Manager WordPress plugin before 7.6.2 does not verify a package's configured role restriction when validating a package password, allowing an unauthenticated user who knows the password of a role-restricted package to obtain a download key and download the protected file. |
| 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 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 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 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. |
