Devolutions Server versions 2026.2.16 and earlier have an improper certificate validation vulnerability on LDAPS connections to Active Directory. This flaw allows a network-positioned attacker to intercept privileged directory service credentials by presenting a spoofed domain controller certificate.
AI Analysis
Technical Summary
The vulnerability in Devolutions Server 2026.2.16 and earlier arises from improper validation of certificates used in LDAPS connections to Active Directory. This weakness enables a network attacker to perform a man-in-the-middle attack by spoofing a domain controller certificate, thereby intercepting privileged credentials transmitted over the directory service connection.
Potential Impact
An attacker with network positioning can intercept privileged credentials used in Active Directory communications, potentially leading to unauthorized access or credential compromise. The vulnerability specifically affects the security of LDAPS connections by allowing spoofed certificates to be accepted.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
