Sauter EY-modulo 5 ecos 5 ecos505 up to 3.1.x Webserver improper validation of syntactic correctness of input

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 Sauter Modulo 6 Devices modu680-AS, Modulo 6 Devices modu660-AS, Modulo 6 Devices modu612-LC, EY-modulo 5 modu 5 modu524, EY-modulo 5 modu 5 modu525, EY-modulo 5 ecos 5 ecos504 and EY-modulo 5 ecos 5 ecos505 up to 3.1.x. It has been declared as critical. Affected by this vulnerability is an unknown code block of the component Webserver. The manipulation with an unknown input leads to a improper validation of syntactic correctness of input vulnerability. The CWE definition for the vulnerability is CWE-1286. The product receives input that is expected to be well-formed - i.e., to comply with a certain syntax - but it does not validate or incorrectly validates that the input complies with the syntax. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A low privileged remote attacker can corrupt the webserver users storage on the device by setting a sequence of unsupported characters which leads to deletion of all previously configured users and the creation of the default Administrator with a known default password.

The weakness was shared by Damian Pfammatter and Daniel Hulliger as vde-2025-060. It is possible to read the advisory at sauter.csaf-tp.certvde.com.
