CVE-2010-0217: Zeacom Chat Server

Medium severity, CVSS 5.8. EPSS: 1.3% chance of exploitation in the next 30 days.

Zeacom Chat Server before 5.1 uses too short a random string for the JSESSIONID value, which makes it easier for remote attackers to hijack sessions or cause a denial of service (Chat Server crash or Tomcat daemon crash) via a brute-force attack.

Affected products

• Zeacom Chat Server: up to and including 5.0
