Reliance on Cookies without Validation and Integrity Checking

Hermes WebUI before 0.51.368 contains an authorization bypass vulnerability in the get_profile_cookie() function that accepts unauthenticated profile names from the hermes_profile cookie. An authenticated attacker can forge the hermes_profile cookie value to bypass profile-scoped authorization checks and access sessions, files, and resources across different profiles.Show less

Concrete CMS 9.5.0 and below is vulnerable to IDOR in surveys. To be vulnerable, a site would have to be configured in such a way that both public and private surveys are present on the site. An unauthenticated attacker can vote in the restricted survey by submitting the restricted optionID through the public survey’s endpoint. The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 6.3 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N.

Authentication bypass vulnerabilities in the GlobalProtect portal and gateway of Palo Alto Networks PAN-OS® software allows the attacker to bypass security restrictions and establish an unauthorized VPN connection. Panorama and Cloud NGFW are not impacted by these issues.Show less

Serendipity is a PHP-powered weblog engine. In versions 2.6-beta2 and below, the serendipity_setCookie() function in include/functions_config.inc.php uses $_SERVER['HTTP_HOST'] without validation as the domain parameter of setcookie(). An attacker who can influence the Host header at login time, such as via MITM, reverse proxy misconfiguration, or load balancer manipulation, can force authentication cookies including session tokens and auto-login tokens to be scoped to an attacker-controlled domain. This enables session fixation, token leakage to attacker-controlled infrastructure, and privilege escalation if an admin logs in under a poisoned Host header. This issue has been fixed in version 2.6.0.Show less

Rack::Session is a session management implementation for Rack. From 2.0.0 to before 2.1.2, Rack::Session::Cookie incorrectly handles decryption failures when configured with secrets:. If cookie decryption fails, the implementation falls back to a default decoder instead of rejecting the cookie. This allows an unauthenticated attacker to supply a crafted session cookie that is accepted as valid session data without knowledge of any configured secret. Because this mechanism is used to load session state, an attacker can manipulate session contents and potentially gain unauthorized access. This vulnerability is fixed in 2.1.2.Show less

The Debugger & Troubleshooter plugin for WordPress was vulnerable to Unauthenticated Privilege Escalation in versions up to and including 1.3.2. This was due to the plugin accepting the wp_debug_troubleshoot_simulate_user cookie value directly as a user ID without any cryptographic validation or authorization checks. The cookie value was used to override the determine_current_user filter, which allowed unauthenticated attackers to impersonate any user by simply setting the cookie to their target user ID. This made it possible for unauthenticated attackers to gain administrator-level access and perform any privileged actions including creating new administrator accounts, modifying site content, installing plugins, or taking complete control of the WordPress site. The vulnerability was fixed in version 1.4.0 by implementing a cryptographic token-based validation system where only administrators can initiate user simulation, and the cookie contains a random 64-character token that must be validated against database-stored mappings rather than accepting arbitrary user IDs.Show less

Plack::Middleware::Session::Cookie versions through 0.21 for Perl allows remote code execution. Plack::Middleware::Session::Cookie versions through 0.21 has a security vulnerability where it allows an attacker to execute arbitrary code on the server during deserialization of the cookie data, when there is no secret used to sign the cookie.Show less

Liman 0.7 contains a cross-site request forgery vulnerability that allows attackers to manipulate user account settings without proper request validation. Attackers can craft malicious HTML forms to change user passwords or modify account information by tricking logged-in users into submitting unauthorized requests.Show less

WAGO 750-8212 PFC200 G2 2ETH RS firmware contains a privilege escalation vulnerability that allows attackers to manipulate user session cookies. Attackers can modify the cookie's 'name' and 'roles' parameters to elevate from ordinary user to administrative privileges without authentication.Show less

An issue was discovered in NJHYST HY511 POE core before 2.1 and plugins before 0.1. The vulnerability stems from the device's insufficient cookie verification, allowing an attacker to directly request the configuration file address and download the core configuration file without logging into the device management backend. By reading the corresponding username and self-decrypted MD5 password in the core configuration file, the attacker can directly log in to the backend, thereby bypassing the front-end backend login page.Show less

The JAY Login & Register plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.4.01. This is due to incorrect authentication checking in the 'jay_login_register_process_switch_back' function with the 'jay_login_register_process_switch_back' cookie value. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id.Show less

COMMAX Biometric Access Control System 1.0.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to access sensitive information and circumvent physical controls in smart homes and buildings by exploiting cookie poisoning. Attackers can forge cookies to bypass authentication and disclose sensitive information.Show less

A reliance on cookies without validation and integrity checking vulnerability in Fortinet FortiWeb 8.0.0 through 8.0.1, FortiWeb 7.6.0 through 7.6.5, FortiWeb 7.4.0 through 7.4.10, FortiWeb 7.2.0 through 7.2.11, FortiWeb 7.0.0 through 7.0.11 may allow an unauthenticated attacker to execute arbitrary operations on the system via crafted HTTP or HTTPS request via forged cookies, requiring prior knowledge of the FortiWeb serial number.Show less

In Brave Browser Desktop versions prior to 1.83.10 that have the split view feature enabled, the "Open Link in Split View" context menu item did not respect the SameSite cookie attribute. Therefore SameSite=Strict cookies would be sent on a cross-site navigation using this method.Show less

NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, an insecure view count mechanism in the forum page allows an unauthenticated attacker to artificially increase the view count. The application relies on a client-side cookie (nl-topic-[tid]) (or session variable for guests) to determine if a view should be counted. When a client does not provide the cookie, every page request increments the counter, leading to incorrect view metrics. This issue has been patched in version 2.2.0.Show less

The WP 2FA with Telegram plugin for WordPress is vulnerable to Two-Factor Authentication Bypass in versions up to, and including, 3.0. This is due to the two-factor code being stored in a cookie, which makes it possible to bypass two-factor authentication.Show less
