Critical Logsign Vulnerability Allows Remote Authentication Bypass, Posing Severe Security Risks
A severe security flaw (CVE-2025-1044) has been discovered in Logsign's Unified SecOps Platform, enabling remote attackers to bypass authentication mechanisms without requiring credentials. This critical vulnerability, which affects systems using TCP port 443, could lead to unauthorized access, data breaches, and potential system compromise. Organizations are urged to update to version 6.4.32 immediately to patch the flaw and safeguard their systems from exploitation.

Logsign Vulnerability Exposes Systems to Remote Authentication Bypass
A critical vulnerability has been discovered in Logsign's Unified SecOps Platform, which could allow remote attackers to bypass the system's authentication processes entirely. Tracked as CVE-2025-1044, this flaw has been assigned a CVSS score of 9.8, making it a serious security risk for affected systems.
Vulnerability Overview: The flaw resides in the web service of Logsign’s Unified SecOps Platform, which typically operates on TCP port 443. The issue stems from an improper implementation of the platform's authentication algorithm. This vulnerability allows attackers to bypass authentication without needing valid credentials, enabling unauthorized access to sensitive data and systems.
Given the nature of the flaw, attackers don’t need to authenticate or interact with users to exploit it, making it especially dangerous for organizations using the platform.
Impact and Risk: Exploiting this vulnerability could lead to unauthorized access, data breaches, and significant disruption of operations. Attackers could escalate privileges, access sensitive information, and even execute remote code, posing a threat to the platform’s confidentiality, integrity, and availability.
Security Measures: Security researchers Abdessamad Lahlali and Smile Thanapattheerakul from Trend Micro’s Zero Day Initiative (ZDI) discovered and reported the issue. The timeline of the discovery and reporting is as follows:
- September 26, 2024: Vulnerability reported to Logsign.
- February 5, 2025: Public release of the advisory.
- February 5, 2025: Updated advisory with additional details.
Logsign has since issued an update (version 6.4.32) to address this flaw and other related security issues. Users are urged to apply this update immediately to safeguard against potential exploitation.
Recommended Actions: Organizations using Logsign’s Unified SecOps Platform should take the following steps:
- Apply the update (version 6.4.32) to fix the authentication bypass issue.
- Restrict access to TCP port 443 via firewalls.
- Implement multi-factor authentication (MFA) to strengthen system security.
- Monitor system logs for unusual activities and potential unauthorized access.
Conclusion: This vulnerability highlights the critical importance of robust authentication mechanisms in cybersecurity platforms. Organizations that rely on Logsign’s Unified SecOps Platform must act swiftly to mitigate the risks posed by CVE-2025-1044 to avoid severe security breaches and operational disruptions.
