Common Weakness Enumeration

CWE-305

Allowed

Authentication Bypass by Primary Weakness

Abstraction: Base · Status: Draft

The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.

300 vulnerabilities reference this CWE, most recent first.

Details

A vulnerability has been identified in SIMATIC HMI United Comfort Panels (All versions). Affected devices insufficiently validate authentication attempts as the information given can be truncated to match only a set number of characters versus the whole provided string. This could allow a remote attacker to discover user passwords and obtain access to the Sm@rt Server via a brute-force attack.

Vulnerability from github – Published: 2022-01-27 15:23 – Updated: 2022-02-07 22:34
VLAI
Summary
Authentication Bypass in ADOdb/ADOdb
Details

Impact

An attacker can inject values into a PostgreSQL connection string by providing a parameter surrounded by single quotes.

Depending on how the library is used in the client software, this may allow an attacker to bypass the login process, gain access to the server's IP address, etc.

Patches

The vulnerability is fixed in ADOdb versions 5.20.21 (952de6c4273d9b1e91c2b838044f8c2111150c29) and 5.21.4 or later (b4d5ce70034c5aac3a1d51d317d93c037a0938d2).

The simplest patch is to delete line 29 in drivers/adodb-postgres64.inc.php:

diff --git a/drivers/adodb-postgres64.inc.php b/drivers/adodb-postgres64.inc.php
index d04b7f67..729d7141 100644
--- a/drivers/adodb-postgres64.inc.php
+++ b/drivers/adodb-postgres64.inc.php
@@ -26,7 +26,6 @@ function adodb_addslashes($s)
 {
    $len = strlen($s);
    if ($len == 0) return "''";
-   if (strncmp($s,"'",1) === 0 && substr($s,$len-1) == "'") return $s; // already quoted

    return "'".addslashes($s)."'";
 }

Workarounds

Ensure the parameters passed to ADOConnection::connect() or related functions (nConnect(), pConnect()) are not surrounded by single quotes.

GHSA-6HQG-WJ7G-983R

Vulnerability from github – Published: 2026-05-04 15:31 – Updated: 2026-06-30 03:36
VLAI
Details

A flaw was found in the AAP gateway. The user auto-link strategy, introduced in AAP 2.6, automatically links an external Identity Provider (IDP) identity to an existing AAP user account based on email matching without verifying email ownership. This allows a remote attacker to potentially hijack a victim's account or gain unauthorized access to other accounts, including administrative accounts, by manipulating the IDP-provided email.
