New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
SynopsisA job scheduling and management system hosted on the remote web server is affected by multiple vulnerabilities.
DescriptionThe version of Jenkins running on the remote web server is prior to 2.186 or is a version of Jenkins LTS prior to 2.176.2. It is, therefore, affected by multiple vulnerabilities:
- An arbitrary file write vulnerability exists due to an incomplete fix for SECURITY-1074, the improper validation of the file parameter definition. An authenticated, remote attacker can exploit this, via a file name with a relative path escaping the base directory, to write arbitrary files on the remote host.
- A security bypass vulnerability exists due to insufficent validaiton of CSRF tokens. An unauthenticated, remote attacker can exploit this, after obtaining the CSRF token of another user, to bypass CSRF protections and implement a CSRF attack. (CVE-2019-10353)
- An information disclosure vulnerability exists in the Stapler web framework due to inadequit permission control of view fragments. An authenticated, remote attacker can exploit this, to disclose potentially sensitive information. (CVE-2019-10354)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade Jenkins to version 2.186 or later, Jenkins LTS to version 2.176.2 or later.
