CVE-2025-6445 is a critical directory traversal vulnerability in ServiceStack's FindType method that allows remote attackers to execute arbitrary code without authentication. The vulnerability stems from insufficient path validation in file operations, enabling attackers to traverse the filesystem and execute malicious code in the context of the affected application process. With a CVSS score of 8.1 and network-based attack vector, this vulnerability poses significant risk to ServiceStack deployments, though exploitation requires application-level interaction with the vulnerable FindType method.
ServiceStack GetErrorResponse Improper Input Validation NTLM Relay Vulnerability. This vulnerability allows remote attackers to relay NTLM credentials on affected installations of ServiceStack. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the implementation of the GetErrorResponse method. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to relay NTLM credentials in the context of the current user. Was ZDI-CAN-25834.
ServiceStack before 5.9.2 mishandles JWT signature verification unless an application has a custom ValidateToken function that establishes a valid minimum length for a signature. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
ServiceStack ServiceStack Framework 4.5.14 is affected by: Cross Site Scripting (XSS). Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
