Detailsinfo

A vulnerability, which was classified as critical, has been found in Chargemap (the affected version unknown). Affected by this issue is an unknown part of the component WebSocket Backend. The manipulation with an unknown input leads to a session expiration vulnerability. Using CWE to declare the problem leads to CWE-613. According to WASC, "Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization." Impacted is confidentiality, integrity, and availability. CVE summarizes:

The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.
