CVE-2015-5320

Status: ModifiedMedium (5)—

Jenkins before 1.638 and LTS before 1.625.2 do not properly verify the shared secret used in JNLP slave connections, which allows remote attackers to connect as slaves and obtain sensitive information or possibly gain administrative access by leveraging knowledge of the name of a slave.

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).
