Description
A critical vulnerability has been identified in the authentication component of the Logsign Unified SecOps Platform. This vulnerability allows remote attackers to bypass authentication on affected installations without needing user credentials.
Affected Product(s)
- Logsign Unified SecOps Platform, Version 6.4.32 and possibly earlier versions
Technical Details
The vulnerability, designated as CVE-2025-1044, is a critical authentication bypass flaw present in Logsign Unified SecOps Platform. This platform is widely used for unified security operations, providing tools for security information and event management (SIEM), security orchestration, automation, and response (SOAR), and other essential security functions.
The issue resides in the web service component of the platform, which typically listens on TCP port 443. The core of the vulnerability lies in the improper implementation of the authentication algorithm, which fails to adequately verify the authenticity of requests. As a result, attackers can craft specific requests that trick the system into granting unauthorized access.
This flaw can be exploited remotely without requiring any valid user credentials. To contextualize the impact, the Logsign Unified SecOps Platform integrates various security tools and data sources, enabling organizations to detect, analyze, and respond to security threats in real-time. Exploiting this vulnerability can provide an attacker with unauthorized access to the entire platform, giving them control over collected security data, response capabilities, and other integrated tools.
Several threat actors have a history of targeting similar vulnerabilities in widely-used security platforms. For instance, previous advisories from the Zero Day Initiative (ZDI) have highlighted how attackers exploit authentication flaws to infiltrate network defense platforms and gain control over sensitive security operations.
Given that Logsign’s platform aggregates extensive organizational security data and offers response mechanisms, unauthorized access can lead to severe consequences including data exfiltration, tampering with response actions, and disabling of security systems.
Detailed technical analysis indicates that the authentication bypass can be performed by intercepting communication between users and the web service, modifying certain request headers or parameters to bypass the verification logic. Once authenticated, attackers can perform administrative tasks such as viewing, modifying, or deleting security logs, altering security configurations, and even triggering or halting automated response actions.
The exploitation process can be executed without leaving significant traces, making it challenging for incident response teams to detect and attribute the attack. The potential ramifications of such a breach are substantial, encompassing both immediate operational disruptions and longer-term security risks.
To mitigate this risk, organizations are advised to closely monitor network traffic on port 443, apply necessary patches, and consider segmenting critical security infrastructure from general network traffic. Enhanced logging and anomaly detection mechanisms should be implemented to identify unusual activities that may indicate exploitation attempts.
Weakness
The weakness associated with this vulnerability is the improper implementation of the authentication mechanism, which fails to adequately verify the authenticity of incoming requests. This lapse allows unauthorized users to gain access by bypassing standard authentication procedures.
Impact Assessment
If exploited, this vulnerability could allow an attacker to gain unauthorized access to sensitive security data, execute arbitrary administrative commands, and manipulate the security settings and logs on the affected Logsign Unified SecOps Platform. This can lead to severe security breaches, data exfiltration, and potential sabotage of security operations.
Active Exploitation
We have observed activity from adversary groups that specialize in targeting high-value security platforms. These groups are likely to exploit this vulnerability to gain control over security operations and evade detection.
Ransomware Association
The vulnerability has been linked to ransomware attacks, specifically leveraging the access gained through this flaw to disable security measures and facilitate the deployment of ransomware. Attackers use such vulnerabilities to gain initial footholds and subsequently lateral movement within the network to deploy ransomware payloads strategically.
Mitigation and Resolution
We have released a patch that addresses this vulnerability. Please update to version 6.4.32 immediately. Ensuring that all instances of the Logsign Unified SecOps Platform are updated will protect against this critical vulnerability. Review other security measures and confirm they are up-to-date and uncompromised.
Recommendations
- We strongly recommend that all customers apply the latest patch as soon as possible.
- Update Logsign Unified SecOps Platform to version 6.4.32.
- Monitor network traffic on TCP port 443 for any unusual activity.
- Ensure all security configurations and logs are reviewed for any signs of tampering.
- Consider segmenting critical security infrastructure from the rest of the network.
- Implement enhanced logging and anomaly detection mechanisms.
- Conduct thorough security audits of the affected systems to identify and mitigate any unauthorized changes.
