Feiten: Cisco heeft een kwetsbaarheid verholpen in Cisco Enterprise Chat and Email (ECE).

Interpretaties: De kwetsbaarheid bevindt zich in de wijze waarop Cisco Enterprise Chat and Email (ECE) onjuiste invoer valideert in zijn chatfunctionaliteiten. Dit kan leiden tot een Denial-of-Service (DoS) situatie, wat mogelijk handmatige interventie vereist om de normale werking te herstellen. Ongeauthenticeerde externe aanvallers kunnen deze kwetsbaarheid misbruiken.

Oplossingen: Cisco heeft updates uitgebracht om de kwetsbaarheid te verhelpen. Zie bijgevoegde referenties voor meer informatie.

CVE-2025-20139 (GCVE-0-2025-20139)

Vulnerability from cvelistv5 – Published: 2025-04-02 16:16 – Updated: 2025-04-02 16:33

Summary

A vulnerability in chat messaging features of Cisco Enterprise Chat and Email (ECE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper validation of user-supplied input to chat entry points. An attacker could exploit this vulnerability by sending malicious requests to a messaging chat entry point in the affected application. A successful exploit could allow the attacker to cause the application to stop responding, resulting in a DoS condition. The application may not recover on its own and may need an administrator to manually restart services to recover.

Severity
