AI description

Automated description summarized from trusted sources.

CVE-2025-40536 is a security control bypass vulnerability affecting SolarWinds Web Help Desk (WHD) software. This flaw enables an unauthenticated attacker to circumvent security measures and access functionalities that are typically restricted to authenticated users. Specifically, the vulnerability allows for the bypass of Cross-Site Request Forgery (CSRF) protections by injecting a particular URI parameter, which then grants access to restricted WebObjects components. This bypass can be a component in a chain of vulnerabilities, potentially leading to more significant compromises, such as unauthenticated remote code execution, when combined with other identified flaws in the software.

Description: SolarWinds Web Help Desk was found to be susceptible to a security control bypass vulnerability that if exploited, could allow an unauthenticated attacker to gain access to certain restricted functionality.
