Detailsinfo

A vulnerability classified as problematic was found in Endress+Hauser MEAC300-FNADE4 (version unknown). This vulnerability affects an unknown function of the component VNC Application. The manipulation with an unknown input leads to a password recoverable vulnerability. The CWE definition for the vulnerability is CWE-257. The storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts. As an impact it is known to affect confidentiality. CVE summarizes:

The VNC application stores its passwords encrypted within the registry but uses DES for encryption. As DES is broken, the original passwords can be recovered.

This vulnerability was named CVE-2025-27459 since 02/26/2025. The exploitation appears to be easy. The attack needs to be approached locally. The exploitation needs additional levels of successful authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1552.

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