SysAid On-Prem Administrative Account Takeover Vulnerability

Historical catalog analysis: CISA added this entry on July 22, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2025-2776 is an improper restriction of XML External Entity Reference (CWE-611) vulnerability affecting SysAid On-Prem. The flaw exists within the Server URL processing functionality. If exploited, this vulnerability could allow an attacker to achieve administrator account takeover and utilize file read primitives.

Exposure and applicability

This vulnerability is applicable to healthcare organizations utilizing the on-premises version of SysAid for IT Service Management (ITSM). In a clinical environment, ITSM tools are frequently used by IT and clinical engineering teams to track tickets, manage medical device inventories, and coordinate infrastructure maintenance.

Because this flaw allows for administrative account takeover, an attacker could potentially gain elevated privileges within the service desk environment. This creates a risk to the confidentiality of electronic Protected Health Information (ePHI) if such data is stored within tickets or configuration files, and it may threaten operational resilience by allowing unauthorized changes to critical IT service workflows.

Remediation priorities

Based on our analysis, healthcare security leaders should prioritize the following actions to reduce exposure:

1. Version Identification: Determine if the current SysAid On-Prem deployment is an affected version. This is a prerequisite for any further mitigation.
2. Vendor Patching: Apply mitigations or updates as specified by the vendor instructions. This is the primary method for addressing the underlying XML processing flaw.
3. Privilege Review: Audit administrative accounts within SysAid to ensure the principle of least privilege is applied, which could limit the impact if an account takeover occurs.
4. Network Segmentation: Ensure the on-premises SysAid server is isolated from direct public internet exposure and restricted to authorized internal networks to reduce the likelihood of external exploitation.

How to validate remediation

To verify that the risk has been reduced, organizations should employ the following methods:

• Version Verification: Confirm through the system administration panel that the installed version matches the patched or mitigated version recommended by the vendor.
• Configuration Audit: Review server logs for unauthorized attempts to access sensitive files or unusual administrative login patterns that may indicate attempted exploitation of file read primitives.
• Access Control Validation: Verify that only necessary personnel have administrative rights, reducing the surface area available for account takeover.

Limits and open questions

Applying vendor mitigations could reduce the likelihood of this specific vulnerability being exploited, but it does not guarantee total prevention of all account takeover vectors. It remains unknown whether this vulnerability has been utilized in active ransomware campaigns. Additionally, while CISA has established a remediation deadline for federal agencies, this date is a regulatory requirement for those specific entities and not a legal mandate for private healthcare providers.
