Sielco PolyEco1000 is vulnerable to a session hijack vulnerability due to the cookie being vulnerable to a brute force attack, lack of SSL, and the session being visible in requests.

Weakness

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

Affected Software

Name Vendor Start Version End Version
Polyeco500_firmware Sielco 1.7.0 (including) 1.7.0 (including)
Polyeco500_firmware Sielco 10.16 (including) 10.16 (including)

Extended Description

Such a scenario is commonly observed when:

In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
