SysAid Patches 4 Critical Flaws Enabling Pre-Auth RCE (CVE-2025-2775 to 2778)

In today’s fast-evolving cybersecurity landscape, SysAid’s on-premise deployments are under the microscope. Critical vulnerabilities (CVE-2025-2775, CVE-2025-2776, CVE-2025-2777, and CVE-2025-2778) allow attackers to exploit XML External Entity (XXE) injection flaws that can escalate to remote code execution (RCE) without authentication. This comprehensive guide explains the nature of these vulnerabilities, how they can be exploited, and why updating your SysAid instance immediately is imperative.

What Are the SysAid Vulnerabilities (CVE-2025-2775 to 2778)?

SysAid’s on-premise software was recently found to contain four major vulnerabilities. These flaws can be summarized as:

• CVE-2025-2775 & CVE-2025-2776: Pre-authenticated XXE injections on the /mdm/checkin endpoint.
• CVE-2025-2777: An additional pre-authenticated XXE injection within the /lshw endpoint.
• CVE-2025-2778: A chained operating system command injection vulnerability discovered by a third party.

These vulnerabilities interact in a way where an attacker could submit a carefully crafted HTTP POST request that manipulates XML input. The consequences range from Server-Side Request Forgery (SSRF) to full-blown remote code execution, potentially exposing sensitive local files like the InitAccount.cmd file which stores administrative credentials in plaintext.

How Do Attackers Exploit These Flaws?

Attackers leverage the XXE injection flaws by injecting unsafe XML entities into the SysAid application. This allows them to force the application to process external XML that can lead to dangerous outcomes:

• Extraction of sensitive local files.
• Chaining the XXE issues with a command injection issue to achieve RCE.

For a more detailed explanation of XXE attacks, you can refer to the comprehensive guide on HackerOne: XXE Exploitation.

Understanding SSRF and Its Role in SysAid Exploitation

When unsafe XML is parsed by the server, it can lead to a Server-Side Request Forgery (SSRF). SSRF attacks allow malicious actors to craft requests from the server-side to internal or external endpoints. This creates an execution chain where, combined with command injection vulnerabilities, complete system takeover may be achieved.

Urgent Patching Guide for SysAid 24.4.60 b16 and Beyond

SysAid has addressed these vulnerabilities in the on-premise version 24.4.60 b16 released in early March 2025. IT administrators are strongly urged to:

1. Confirm your installation version of SysAid.
2. Immediately update to version 24.4.60 b16 or later.
3. Review and implement any additional security measures recommended in the patch release notes.

You can directly view SysAid’s patch documentation for specific instructions and further details.

Real-World Implications and Local Relevance

For IT administrators and cybersecurity professionals, especially those managing enterprise systems or operating in regions where threat actors are increasingly active, it is critical to not only apply patches but also review configurations for potential exploitation avenues. Incidents of ransomware groups, like those seen with previous SysAid vulnerabilities (e.g., CVE-2023-47246), have directly affected organizations and resulted in costly downtime.

If you are an IT admin based in metropolitan areas or regions with high enterprise density, such as Toronto or New York, please note that localized threat environments demand rapid response times and proactive security audits.

How Can You Safeguard Your SysAid Environment?

Here are some actionable recommendations to build a robust defense against these types of vulnerabilities:

• Regularly Update: Ensure your SysAid version is updated to the latest release (24.4.60 b16 or newer) to avoid known vulnerabilities.
• Audit Configurations: Conduct regular security audits and reviews of system configurations.
• Monitor Traffic: Implement network monitoring to quickly detect suspicious outbound requests that could indicate exploitation attempts.
• Educate Your Team: Ensure that your IT and cybersecurity teams are well-versed in the latest exploitation techniques and patch management best practices.

Conclusion & Call-to-Action

SysAid’s critical vulnerabilities from CVE-2025-2775 to CVE-2025-2778 serve as a stark reminder of the evolving threat landscape. These flaws can be easily exploited via XXE injections that pave the way for SSRF and ultimately RCE, underscoring the urgent need for timely patching. Update SysAid immediately to shield your system from potential attackers and safeguard sensitive data.
