CVE-2025-22238 is a directory traversal vulnerability identified in VMware SALT, specifically affecting versions 3006.x and 3007.x. The vulnerability arises during the minion file cache creation process on the master server, where the default cache implementation fails to properly sanitize file paths. This flaw allows an attacker to craft malicious input that traverses directories outside the intended cache directory, enabling the attacker to write or overwrite arbitrary 'cache' files elsewhere on the filesystem. The vulnerability requires local access with high privileges (PR:H) and user interaction (UI:R), indicating that an attacker must have authenticated access to the system and perform some action to trigger the exploit. The CVSS v3.1 base score is 4.2, reflecting a medium severity level. The attack vector is local (AV:L), and while confidentiality is not impacted (C:N), the integrity of the system is at risk (I:H) due to the ability to overwrite files, potentially leading to unauthorized code execution or system manipulation. Availability is not affected (A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is categorized as a directory traversal issue, which is a common security weakness that can lead to privilege escalation or persistent compromise if exploited effectively.

For European organizations utilizing VMware SALT versions 3006.x or 3007.x, this vulnerability poses a risk primarily to system integrity. An attacker with authenticated local access could exploit the directory traversal flaw to overwrite critical cache files or other files on the system, potentially leading to unauthorized code execution or manipulation of system behavior. This could compromise the security of configuration management and automation workflows, which are critical in enterprise environments. Although the vulnerability does not directly impact confidentiality or availability, the integrity compromise could facilitate further attacks, including lateral movement or persistence within the network. Organizations in sectors with stringent compliance requirements, such as finance, healthcare, and critical infrastructure, may face regulatory and operational risks if this vulnerability is exploited. The requirement for high privileges and user interaction limits the attack surface but does not eliminate risk, especially in environments with multiple administrators or where insider threats are a concern.

1. Restrict access to VMware SALT master servers to trusted administrators only, minimizing the number of users with high privileges. 2. Implement strict access controls and monitoring on the filesystem directories used by SALT to detect unauthorized file modifications. 3. Employ application whitelisting and integrity monitoring tools to alert on unexpected changes to cache or configuration files. 4. Regularly audit user activities and enforce multi-factor authentication for all administrative access to reduce the risk of credential compromise. 5. Until an official patch is released, consider isolating SALT master servers in segmented network zones with limited access to reduce exposure. 6. Review and harden SALT configuration to limit the scope of file operations and validate inputs where possible. 7. Stay updated with VMware advisories and apply patches promptly once available. 8. Conduct internal penetration testing focusing on local privilege escalation vectors to identify potential exploitation paths related to this vulnerability.
