Description
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.

Comprehensive Technical Analysis of EUVD-2024-52685
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2024-52685 affects Teedy versions between 1.9 and 1.12, specifically when the LDAP connection is activated. The issue arises from improper sanitization of user input in the username field of the login form, leading to LDAP injection vulnerabilities. This allows unauthenticated attackers to perform various malicious actions, including creating arbitrary accounts and spraying passwords.
Severity Evaluation:
- Base Score: 9.8 (CVSS:3.1)
- Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
The high base score of 9.8 indicates a critical vulnerability. The CVSS vector string highlights the following:
- Attack Vector (AV): Network (N)
- Attack Complexity (AC): Low (L)
- Privileges Required (PR): None (N)
- User Interaction (UI): None (N)
- Scope (S): Unchanged (U)
- Confidentiality (C): High (H)
- Integrity (I): High (H)
- Availability (A): High (H)
This vulnerability poses a significant risk due to its ease of exploitation and the severe impact on confidentiality, integrity, and availability.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- LDAP Injection: Attackers can inject malicious LDAP queries into the username field to manipulate the authentication process.
- Account Creation: By exploiting the LDAP injection, attackers can create arbitrary accounts, potentially gaining unauthorized access.
- Password Spraying: Attackers can use the vulnerability to attempt multiple passwords across many accounts without triggering account lockouts.
Exploitation Methods:
- Crafting Malicious Input: Attackers can craft specific input strings designed to exploit the LDAP injection vulnerability.
- Automated Tools: Use of automated scripts or tools to perform password spraying and account creation at scale.
3. Affected Systems and Software Versions
Affected Software:
- Teedy versions 1.9 to 1.12 with LDAP connection activated.
Affected Systems:
- Any system running the affected versions of Teedy with LDAP integration enabled.
4. Recommended Mitigation Strategies
Immediate Actions:
- Disable LDAP Integration: Temporarily disable LDAP integration until a patch is applied.
- Input Sanitization: Implement robust input sanitization and validation mechanisms to prevent LDAP injection.
- Monitoring: Increase monitoring for suspicious login attempts and account creation activities.
Long-Term Solutions:
- Patch Management: Apply the latest patches and updates provided by the vendor.
- Security Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
- User Education: Educate users about the risks of LDAP injection and the importance of secure password practices.
5. Impact on European Cybersecurity Landscape
The vulnerability poses a significant threat to organizations within the European Union that rely on Teedy for their operations. The potential for unauthorized access and data breaches can lead to severe financial and reputational damage. Compliance with regulations such as GDPR may also be compromised, leading to legal repercussions.
6. Technical Details for Security Professionals
Technical Overview:
- LDAP Injection: The vulnerability stems from the lack of proper input sanitization in the username field, allowing attackers to inject LDAP queries.
- Exploitation: Attackers can use crafted input to manipulate LDAP queries, leading to unauthorized actions such as account creation and password spraying.
Detection and Response:
- Log Analysis: Analyze login attempt logs for unusual patterns or malformed LDAP queries.
- Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious LDAP query patterns.
- Incident Response: Have a well-defined incident response plan to quickly address and mitigate any detected exploitation attempts.
