2) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU22264

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:U/RC:C]

CVE-ID: CVE-2019-10469

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote user to perform SSRF attacks.

The vulnerability exists due to the affected plugin does not perform permission checks on a method implementing form validation. A remote authenticated user with Overall/Read permission can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems, capturing credentials stored in Jenkins.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
