Intel(R) oneAPI Toolkit and component software…: Uncontrolled Search Path Element

Published Updated By the CyberSecBulletin desk

CVE-2023-22355 is a high-severity uncontrolled search path element vulnerability in Intel(R) oneAPI Toolkit and component software installers, 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 attacker with a low-privileged account, without any action from a user. Affected Intel(R) oneAPI Toolkit and component software installers versions: before version 4.3.0.251. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.21% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Advisor to 2023.0 or a later version.
  2. Update Cpu Runtime to 2023.0 or a later version.
  3. Update Distribution For Python to 2023.0 or a later version.
  4. Read the advisory on intel.com for workarounds and exact fixed builds.

Official description

Uncontrolled search path in some Intel(R) oneAPI Toolkit and component software installers before version 4.3.0.251 may allow an authenticated user to potentially enable escalation of privilege via local access.

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.
