CVE-2026-17071: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVE-2026-17071 is a path traversal vulnerability in IBM i versions 7.3, 7.4, 7.5, and 7.6. It allows a remote authenticated attacker to perform unauthorized file manipulation by exploiting improper limitation of pathnames to restricted directories. The vulnerability has a low severity score and does not impact confidentiality or availability but can affect integrity.
AI Analysis
Technical Summary
IBM i versions 7.3 through 7.6 contain a CWE-22 path traversal vulnerability that permits remote authenticated users to manipulate files outside intended directories. This occurs due to insufficient validation of pathname inputs, allowing attackers to traverse directories and potentially modify files. The CVSS 3.1 base score is 2.7, reflecting low impact with no confidentiality or availability loss, only limited integrity impact. No vendor advisory or patch information is currently available.
Potential Impact
The vulnerability allows remote authenticated attackers to perform file manipulation outside of restricted directories, potentially altering files improperly. There is no impact on confidentiality or availability. The integrity impact is limited. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict remote authenticated access to trusted users only and monitor for suspicious file manipulation activities related to IBM i systems.
