Technical Analysis
IBM WebSphere Application Server - Liberty versions 17.0.0.3 through 26.0.0.9 contain a CWE-22 path traversal vulnerability. A local attacker can exploit this by providing a specially crafted application archive that causes files to be written outside the intended directory, bypassing pathname restrictions. This could lead to unauthorized file modification or placement on the system.
Potential Impact
The vulnerability allows a local attacker to write files outside the intended directory, which may lead to unauthorized modification of files or insertion of malicious files. Confidentiality is not impacted, and there is no denial of service. The integrity of the system could be compromised due to unauthorized file writes.
Mitigation Recommendations
No explicit patch or remediation information is provided in the input data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is applied, restrict local access to trusted users only and validate application archives before deployment.
