MBS Single-A prior 6_0_0_7 ugw-logread path traversal

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 was found in MBS Single-A, Double-A Profibus, Double-A x-link, Single-X, Double-X CAN, Double-X DALI, Double-X KNX, Double-X LON, Double-X M-Bus, Double-X PROFINET, Double-X x-link, Triple-X KNX+DALI, Triple-X KNX+LON, Triple-X KNX+M-Bus, Triple-X PROFINET+DALI, Triple-X PROFINET+KNX, Triple-X PROFINET+LON and Triple-X PROFINET+M-Bus. It has been classified as critical. This affects the function ugw-logread. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The ugw-logread method allows a remote attacker with user privileges to access arbitrary local files due to insufficient validation of user-supplied input.

The weakness was published by Adrien Rey as VDE-2026-039. It is possible to read the advisory at certvde.com. This vulnerability is uniquely identified as CVE-2026-35082 since 04/01/2026.
