CA eHealth Performance Manager through 6.3.2.12 is affected by Privilege Escalation via a Dynamically Linked Shared Object Library. A regular user must create a malicious library in the writable RPATH, to be dynamically linked when the emtgtctl2 executable is run. The code in the library will be executed as the ehealth user. NOTE: This vulnerability only affects products that are no longer supported by the maintainer

Weakness

The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.

Affected Software

Name Vendor Start Version End Version
Ehealth Broadcom * 6.3.2.12 (including)

Extended Description

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
