A critical vulnerability (CVE-2024-53591) has been identified in Seclore v3.27.5.0 that allows attackers to bypass authentication through brute force attacks. With a CVSS v3.1 score of 9.8 (Critical), this vulnerability poses significant risk to organizations using the affected version of the enterprise rights management solution.
Executive Summary
The vulnerability affects the login page of Seclore v3.27.5.0, enabling remote attackers to gain unauthorized access without valid credentials. The National Vulnerability Database (NVD) classifies this as a Missing Authorization issue (CWE-862), where the system fails to properly restrict access to sensitive functionality.
TL;DR Key Points:
- CVSS 9.8 Critical vulnerability in Seclore v3.27.5.0
- Authentication bypass via brute force attack
- Public PoC available on GitHub
- No vendor patch available as of April 2025
- Workarounds include rate limiting and MFA implementation
Technical Analysis
The vulnerability resides in the authentication mechanism of Seclore’s web interface. Attackers can systematically attempt credential combinations without encountering lockout mechanisms or sufficient rate limiting. The network-based attack vector means exploitation can occur remotely without requiring prior access to the target system.
According to the GitHub advisory, successful exploitation grants full system access equivalent to authenticated users. This includes all privileges associated with the compromised account, potentially leading to complete system compromise. The availability of a public proof-of-concept on GitHub increases the likelihood of widespread exploitation attempts.
Affected Systems and Impact
The vulnerability specifically targets Seclore version 3.27.5.0. Organizations running this version should consider immediate mitigation measures. The impact extends across all three pillars of security:
| Impact Area | Severity |
|---|---|
| Confidentiality | High (Unauthorized data access) |
| Integrity | High (Data modification possible) |
| Availability | High (Potential service disruption) |
Mitigation Strategies
While awaiting an official patch from Seclore Technologies, organizations should implement the following workarounds:
- Deploy network-level rate limiting for authentication requests
- Enable multi-factor authentication for all user accounts
- Monitor authentication logs for unusual patterns
- Restrict access to the login interface using network controls
Security teams should prioritize monitoring for the following indicators of compromise:
- Unusual authentication attempts from single IP addresses
- Multiple failed login attempts followed by successful access
- Authentication logs showing rapid sequential attempts
Detection and Response
Security operations teams can use the following SIEM query to detect potential exploitation attempts:
index=auth (source="seclore_auth.log" AND (status=failure AND count > 5) OR (status=success AFTER status=failure)) | stats count by src_ip, userThis query identifies both brute force attempts and successful logins following multiple failures. The EPSS score of 0.02% suggests low probability of mass exploitation, but targeted attacks remain a concern.
Conclusion
CVE-2024-53591 represents a significant threat to organizations using Seclore v3.27.5.0 due to the combination of high impact and available exploit code. While the vendor works on an official patch, security teams should implement temporary controls and monitor authentication activity closely.
The availability of a public proof-of-concept increases urgency for mitigation. Organizations should track updates from Seclore Technologies and the NVD for patch availability and additional guidance.
