Summary

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

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leveraging/Manipulating Configuration File Search Paths
    This attack loads a malicious resource into a program's standard path used to bootstrap and/or provide contextual information for a program like a path variable or classpath. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker. A standard UNIX path looks similar to this If the attacker modifies the path variable to point to a locale that includes malicious resources then the user unwittingly can execute commands on the attackers' behalf: This is a form of usurping control of the program and the attack can be done on the classpath, database resources, or any other resources built from compound parts. At runtime detection and blocking of this attack is nearly impossible, because the configuration allows execution.
