Siemens Siveillance Video 2023 Event Server deserialization

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.

Detailsinfo

A vulnerability, which was classified as very critical, was found in Siemens Siveillance Video 2020, Siveillance Video 2021, Siveillance Video 2022 and Siveillance Video 2023 (affected version not known). This affects some unknown functionality of the component Event Server Component. The manipulation with an unknown input leads to a deserialization vulnerability. CWE is classifying the issue as CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability has been identified in Siveillance Video 2020 R2 (All versions < V20.2 HotfixRev14), Siveillance Video 2020 R3 (All versions < V20.3 HotfixRev12), Siveillance Video 2021 R1 (All versions < V21.1 HotfixRev12), Siveillance Video 2021 R2 (All versions < V21.2 HotfixRev8), Siveillance Video 2022 R1 (All versions < V22.1 HotfixRev7), Siveillance Video 2022 R2 (All versions < V22.2 HotfixRev5), Siveillance Video 2022 R3 (All versions < V22.3 HotfixRev2), Siveillance Video 2023 R1 (All versions < V23.1 HotfixRev1). The Event Server component of affected applications deserializes data without sufficient validations. This could allow an authenticated remote attacker to execute code on the affected system.

The weakness was published 05/09/2023 as ssa-789345. The advisory is shared at cert-portal.siemens.com. This vulnerability is uniquely identified as CVE-2023-30898. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 06/01/2023).
