Two vulnerabilities have been reported in Jenkins, that can be exploited by malicious people to disclose potentially sensitive information and conduct cross-site scripting attacks.
1) Certain unspecified input passed to the "Winstone" component is not properly verified before being used to display files. This can be exploited to disclose the contents of arbitrary files via directory traversal sequences.
Note: This vulnerability only affects installations on the Windows platform using the .war file release.
2) Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerabilities are reported in versions 1.452 and prior, and versions 1.424.3 LTS and prior.
Solution: Update to version 1.454 or version 1.454.6 LTS.
