WordPress Unspecified Directory Traversal Vulnerability

Risk

Medium

Date Discovered

November 19, 2019

Description

WordPress is prone to an unspecified directory-traversal vulnerability because the application fails to sufficiently sanitize user-supplied input. Remote attackers may use a specially crafted request with directory-traversal sequences ('../') to retrieve sensitive information or execute arbitrary code. This may aid in further attacks. WordPress versions prior to 5.2.4 are vulnerable.

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.

Currently we are not aware of any vendor-supplied patches. If you feel we are in error or if you are aware of more recent information, please mail us at: vuldb@securityfocus.com.
