CVE Descriptions

Multiple directory traversal vulnerabilities in F5 BIG-IP before 10.2.2 allow local users with the "Resource Administrator" or "Administrator" role to enumerate and delete arbitrary files via a .. (dot dot) in the name parameter to (1) tmui/Control/jspmap/tmui/system/archive/properties.jsp or (2) tmui/Control/form.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name Source
CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Any system file deletion, for instance under /etc, /boot etc would have a major functionality and operational impact for the device. +----------------------+ + Exploitation Details + +----------------------+ An authenticated user with either "Resource Administrator" or "Administrator" role privileges is able to enumerate files on the operating system and subsequently delete them off the OS level. In order to trigger the flaw, send a HTTP GET request similar to: https://<ip>/tmui/Control/jspmap/tmui/system/archive/properties.jsp?&name=../../../../../etc/passwd Condition: If file does not exist the application will return "File not found." If the file exists, the user can either send, a similar to, the next HTTP POST request or simply click on the Delete button through the GUI -the button will be displayed only if the enumerated file exists-.
