Poly VVX 601 Web Configuration Application random values

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as problematic has been found in Poly Trio 8300, Trio 8500, Trio 8800, Trio C60, CCX 350, CCX 400, CCX 500, CCX 505, CCX 600, CCX 700, EDGE E100, EDGE E220, EDGE E300, EDGE E320, EDGE E350, EDGE E400, EDGE E450, EDGE E500, EDGE E550, VVX 101, VVX 150, VVX 201, VVX 250, VVX 300, VVX 301, VVX 310, VVX 311, VVX 350, VVX 400, VVX 401, VVX 410, VVX 411, VVX 450, VVX 500, VVX 501, VVX 600 and VVX 601. This affects some unknown processing of the component Web Configuration Application. The manipulation with an unknown input leads to a random values vulnerability. CWE is classifying the issue as CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. This is going to have an impact on confidentiality.

The weakness was published 12/29/2023 by Christoph Wolff and Pascal Zenker with modzero AG as MZ-23-01. It is possible to read the advisory at modzero.com. This vulnerability is uniquely identified as CVE-2023-4462. Technical details are unknown but a public exploit is available. The attack technique deployed by this issue is T1600.001 according to MITRE ATT&CK. The advisory points out:

The session tokens generated for the different Poly devices’ web configuration interfaces are using weak randomness. Effectively only one token per second is generated and the tokens can be predicted by an attacker due to a deterministic algorithm based on the time in seconds. This allows attackers to hijack an active administrator session.

The exploit is shared for download at github.com. It is declared as proof-of-concept.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
