e107 Second-Order Code Execution via eval()-Based Deserialization in e_array::unserialize()

e107 prior to version 2.3.8 contains a code execution vulnerability in the e_array deserialization handler that allows an attacker with out-of-band database write access to execute arbitrary PHP code by storing a crafted payload in the user_prefs column. The e_array::unserialize() function in e107_handlers/core_functions.php performs only a prefix check for the string 'array' before passing the stored value to eval(), causing automatic PHP execution whenever the affected user's preferences are materialized through e_user_pref::load().

CamaleonCMS 2.9.2 Privilege Escalation via Parameter Confusion in UsersController

CamaleonCMS version 2.9.2 and earlier contains a privilege escalation vulnerability via insecure direct object reference (IDOR) that allows authenticated low-privileged attackers to overwrite any user's credentials by exploiting a parameter confusion flaw between the authorization filter and action body in the UsersController. Attackers can send a PATCH request to the updated_ajax endpoint setting params[:id] to their own user ID to pass the self-authorization check while simultaneously setting params[:user_id] to a victim's ID, causing the controller to load and mutate the victim's account, including overwriting administrator passwords to achieve full site takeover.

CamaleonCMS 2.9.2 and earlier Missing Authorization via profile Action

CamaleonCMS version 2.9.2 and earlier contains a missing authorization vulnerability in the admin users controller that allows any authenticated user to access any other user's profile data by supplying an arbitrary user ID parameter. Attackers can send a GET request to the admin profile endpoint with an enumerable sequential integer user ID to disclose profile information of any user, including administrators, due to the profile action being excluded from the role validation filter with no compensating ownership check.

CentreStack < 17.4 SQL Injection via x-glad-filter Header

CentreStack before 17.4 contains a SQL injection vulnerability in GladDBFiles.SearchEx() and SearchExUnder() that allows authenticated attackers to execute arbitrary SQL statements by supplying a crafted x-glad-filter request header through the jsondir API endpoint. Attackers can exploit unsanitized interpolation of the Field parameter directly into SQL query strings to write arbitrary files to the server filesystem via PostgreSQL lo_from_bytea() and lo_export() functions, enabling remote code execution.

Attackers can generate valid encrypted EntAcctId values using the static shared encryption key to forge identifiers for any user GUID, including the system-wide cluster settings account, enabling enumeration of hosted tenant domains and administrator identities.

CentreStack before 17.4 contains an XML external entity (XXE) injection vulnerability that allows unauthenticated attackers to exfiltrate arbitrary files by supplying a malicious URL to the SharePoint storage configuration handler. Attackers can send a crafted request to the unauthenticated StorageConfig endpoint causing the server to fetch and parse attacker-controlled XML containing external DTD references, resulting in out-of-band file exfiltration of sensitive files such as Web.config, which may contain database credentials and cryptographic key material.

Attackers can send a malicious StorageConfigure parameter to the jsonimportuserbyupn, jsonimportuserbyupnex, or japiimportuserbyupn endpoints to trigger InternalImportAdUserByUPN(), causing GladinetCloudMonitor.exe to invoke the NetUserAdd Windows API with attacker-controlled credentials and create arbitrary directories on the server filesystem.

Attackers can use the hardcoded key to craft valid x-glad-auth headers and call privileged API endpoints such as acquiretenantbackuptoken to obtain a domain administrator IdentityTicket, enabling a complete unauthenticated remote code execution chain.

NetBSD hdaudio(4) Driver Privilege Bypass Use-After-Free via HDAUDIO_FGRP_SETCONFIG ioctl

NetBSD's hdaudio(4) driver in sys/dev/hdaudio/hdaudio.c contains a missing access control vulnerability that allows unprivileged local attackers to invoke the HDAUDIO_FGRP_SETCONFIG ioctl without elevated permissions by exploiting the absence of an access check on /dev/hdaudioN device nodes. Attackers can repeatedly issue HDAUDIO_FGRP_SETCONFIG from one thread while keeping DMA and IRQs live from a second thread to trigger a use-after-free race condition in hdafg_detach() between stream_stop() and stream_disestablish(), where a latched DMA interrupt dereferences a freed callback pointer, resulting in outcomes ranging from audio-subsystem denial of service and kernel panic to potential local kernel privilege escalation.

Attackers can craft a malicious URL that, when followed by an authenticated victim with edit_settings permissions, executes injected scripts in the application origin to steal session cookies or perform unauthorized actions including user management, file management, and application settings changes.

rsync < 3.5.0 Symlink Following Arbitrary File Overwrite

rsync before 3.5.0 contains a symlink following vulnerability that allows local attackers to overwrite arbitrary files by placing a symlink at a predictable output path such as --log-file, --write-batch, or daemon-mode log and statistics paths. Attackers can exploit rsync's failure to reject symlinks during ancillary file writes to redirect output to arbitrary filesystem locations, achieving local privilege escalation on installations where rsync runs with elevated privileges such as setuid or privileged daemon configurations.

rsync before 3.5.0 contains a symlink race condition vulnerability in the sender's directory scanning logic that allows attackers to cause the sender to enumerate and transfer files outside the module root's intended subtree. Attackers who can create or manipulate symlinks in a path component of the scanned tree can replace a symlink with a directory entry pointing outside the module root between the lstat() call and the subsequent opendir() call, exposing files beyond the intended root in both daemon-mode and non-daemon sender-side scanning.

rsync before 3.5.0 contains a privilege confusion vulnerability in the name-converter subprocess uid/gid mapping that allows local attackers to cause transferred files to be owned by root by influencing name-converter responses to return empty values. When the name-converter subprocess returns an empty response for a uid or gid lookup, rsync incorrectly interprets it as a successful resolution to uid/gid 0 (root) rather than a lookup failure, and if the name-converter also signals fake super-user status, rsync proceeds with root ownership assignments for transferred files.
