Description

This security bulletin contains information about 3 vulnerabilities.


1) Path traversal (CVE-ID: CVE-2019-10352)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the "core/src/main/java/hudson/model/FileParameterValue.java." A remote authenticated attacker with Job/Configure permission can define a file parameter with a file name outside the intended directory.

This vulnerability results in an arbitrary file write on the Jenkins master when scheduling a build.


2) Cross-site request forgery (CVE-ID: CVE-2019-10353)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to the CSRF tokens by default only check user authentication and IP address. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.

This vulnerability allows an attacker to obtain a CSRF token for another user to implement CSRF attacks as long as the victim’s IP address remained unchanged.


3) Authentication bypass using an alternate path or channel (CVE-ID: CVE-2019-10354)

CWE-ID: CWE-288 - Authentication Bypass Using an Alternate Path or Channel

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass permission checks.

The vulnerability exists due to the access control bypass in the Stapler web framework. A remote authenticated attacker can access view fragments directly, bypass permission checks and possibly obtain sensitive information.
