Description


In the DES implementation, the affected product versions use a default key for encryption. Successful exploitation allows an attacker to obtain sensitive information and gain access to the network elements that are managed by the affected products versions.

This issue affects

* FOXMAN-UN product: FOXMAN-UN R16A, FOXMAN-UN R15B, FOXMAN-UN R15A, FOXMAN-UN R14B, FOXMAN-UN R14A, FOXMAN-UN R11B, FOXMAN-UN R11A, FOXMAN-UN R10C, FOXMAN-UN R9C;
* UNEM product: UNEM R16A, UNEM R15B, UNEM R15A, UNEM R14B, UNEM R14A, UNEM R11B, UNEM R11A, UNEM R10C, UNEM R9C.

Understanding This Vulnerability

This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.

The severity rating (HIGH) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.

If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.
