Detailsinfo

A vulnerability classified as critical was found in Mobiliti e-mobi.hu (affected version not known). This vulnerability affects some unknown functionality of the component WebSocket Backend. The manipulation with an unknown input leads to a session expiration vulnerability. The CWE definition for the vulnerability is 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." As an impact it is known to affect 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.

The weakness was presented by Khaled Sarieddine and Mohammad Ali Sayed. The advisory is available at mobiliti.hu. This vulnerability was named CVE-2026-27764 since 02/24/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation.
