PowerStore: Uncontrolled Search Path Element
CVE-2022-32498 is a high-severity uncontrolled search path element vulnerability in PowerStore from Dell, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version v3.0.0.0 as the first without the flaw, so updating PowerStore to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.19% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update PowerStore to v3.0.0.0 or a later version.
- Update Powerstore Command Line Interface to 3.0.0.0-1732745 or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Dell EMC PowerStore, Versions prior to v3.0.0.0 contain a DLL Hijacking vulnerability in PSTCLI. A local attacker can potentially exploit this vulnerability to execute arbitrary code, escalate privileges, and bypass software allow list solutions, leading to system takeover or IP exposure.

The underlying weakness: Uncontrolled Search Path Element
The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
How developers prevent this class of flaw
- Hard-code the search path to a set of known-safe values (such as system directories), or only allow them to be specified by the administrator in a configuration file. Do not allow these settings to be modified by an external party. Be careful to avoid related weaknesses such as CWE-426 and CWE-428.
- When invoking other programs, specify those programs using fully-qualified pathnames. While this is an effective approach, code that uses fully-qualified pathnames might not be portable to other systems that do not use the same pathnames. The portability can be improved by locating the full-qualified paths in a centralized, easily-modifiable location within the source code, and having the code refer to these paths.
- Remove or restrict all environment settings before invoking other programs. This includes the PATH environment variable, LD_LIBRARY_PATH, and other settings that identify the location of code libraries, and any application-specific search paths.
