CVE-2024-8260
Description
An SMB force-authentication vulnerability exists in all versions of OPA. The vulnerability exists due to improper input validation, allowing a user to pass an arbitrary SMB share instead of a Rego file as an argument to OPA CLI or one of the OPA Go library’s functions.
Statement
The SMB force-authentication vulnerability in OPA for Windows builds is classified as moderate severity due to its specific exploitation requirements and potential impact. The flaw arises from improper input validation, allowing an attacker to supply an arbitrary SMB share instead of a Rego file. However, exploitation of this issue necessitates direct access to the OPA CLI or its Go library functions, and the attacker must have the ability to influence the arguments passed to these components. While it could lead to unauthorized access or manipulation of data if exploited, the attack vector is limited and requires specific conditions to be met.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Access Control
Technical Impact: Gain Privileges or Assume Identity
Messages sent with a capture-relay attack allow access to resources which are not otherwise accessible without proper authentication.
