CVE-2024-54852 in Teedy
Summary
by MITRE • 01/30/2025
When LDAP connection is activated in Teedy versions between 1.9 to 1.12, the username field of the login form is vulnerable to LDAP injection. Due to improper sanitization of user input, an unauthenticated attacker is then able to perform various malicious actions, such as creating arbitrary accounts and spraying passwords.

The vulnerability identified as CVE-2024-54852 affects Teedy document management systems version 1.9 through 1.12 where LDAP authentication is enabled. This represents a critical security flaw that undermines the integrity of the authentication mechanism by allowing unauthorized individuals to manipulate the LDAP connection process. The vulnerability specifically targets the username field within the login form, which serves as the primary entry point for authentication attempts and user identification within the system.
The technical root cause of this vulnerability stems from inadequate input validation and sanitization practices within the LDAP connection handling code. When users attempt to authenticate through the web interface, the system fails to properly escape or filter special characters that have significance within LDAP query syntax. This lack of proper input sanitization creates an injection vector that allows attackers to craft malicious LDAP queries through the username field, effectively bypassing normal authentication controls and gaining unauthorized access to the system's user management functions.
From an operational perspective, this vulnerability presents attackers with multiple attack vectors that can be exploited without prior authentication credentials. The ability to perform arbitrary account creation means that attackers can establish persistent access points within the system, potentially creating accounts with elevated privileges or administrative access. Password spraying capabilities further amplify the impact as attackers can systematically attempt to gain access to legitimate user accounts using common password combinations, leveraging the fact that the system's authentication layer is compromised at the input validation stage. This vulnerability directly aligns with CWE-91 and CWE-77 respectively, which address LDAP injection and improper neutralization of special elements used in SQL commands, though adapted for LDAP contexts.
The exploitation of this vulnerability can result in significant security breaches including unauthorized data access, privilege escalation, and potential lateral movement within the network environment where Teedy is deployed. Organizations relying on LDAP integration for user authentication face the risk of complete system compromise if this vulnerability remains unpatched. The attack surface is particularly concerning given that the vulnerability affects a core authentication mechanism that is essential for maintaining system security boundaries and access controls. Security teams should consider this vulnerability as a high-priority issue requiring immediate attention, especially in environments where LDAP integration is actively used for authentication purposes.
Mitigation strategies should include immediate patching of affected Teedy versions to address the input sanitization issues within the LDAP connection handling code. Organizations should also implement network-level controls such as restricting access to LDAP ports and implementing additional authentication layers to reduce the attack surface. Regular security assessments should be conducted to identify similar input validation weaknesses in other authentication mechanisms, and application developers should adopt secure coding practices that properly sanitize all user inputs before processing them in LDAP queries. The implementation of proper input validation frameworks and regular code reviews focused on authentication mechanisms can help prevent similar vulnerabilities from being introduced in future releases, aligning with ATT&CK technique T1110 for credential access and T1078 for valid accounts.
