Status: ModifiedMedium (4.3)—

The org.apache.catalina.connector.Response.encodeURL method in Red Hat JBoss Web 7.1.x and earlier, when the tracking mode is set to COOKIE, sends the jsessionid in the URL of the first response of a session, which allows remote attackers to obtain the session id (1) via a man-in-the-middle attack or (2) by reading a log.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
