CVE-2024-56462 IBM CVE debrief

CVE-2024-56462 is a high-severity vulnerability affecting IBM QRadar versions 7.5.0 through 7.5.0 UP15 Interim Fix 002. The flaw allows a privileged user to upload a malicious backup archive that, when restored, can be leveraged to gain access to the underlying operating system. This represents a path traversal or arbitrary file write scenario within the backup restoration process, where insufficient validation of archive contents permits OS-level compromise. The CVSS 3.1 score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) reflects high impact confidentiality, integrity, and availability impacts, though the attack requires high privileges. The vulnerability was published to NVD on May 27, 2026, with IBM PSIRT as the primary source. Organizations running affected QRadar versions should prioritize applying patches from IBM's support portal and restrict backup restoration privileges to minimize exposure.

Who should care

IBM QRadar administrators, SOC managers, and security architects deploying QRadar SIEM appliances. Organizations subject to compliance requirements mandating SIEM integrity and availability. Managed security service providers operating QRadar instances for multiple clients.

Technical summary

The vulnerability exists in IBM QRadar's backup restoration functionality. A privileged attacker can craft a malicious backup archive containing files designed to overwrite critical OS components or establish persistence mechanisms. When the archive is uploaded and restored through QRadar's administrative interface, the extraction process fails to properly sanitize or validate archive contents, resulting in arbitrary file writes to the underlying operating system. This grants the attacker shell-level access to the QRadar appliance, bypassing application-layer controls. The attack requires network access to the QRadar administrative interface and valid high-privilege credentials, but no user interaction.

Defensive priority

high

Recommended defensive actions

  • Apply IBM-provided patches for QRadar 7.5.0 through 7.5.0 UP15 Interim Fix 002 as referenced in IBM security advisory
  • Restrict backup upload and restoration privileges to only essential administrative accounts
  • Audit recent backup restoration activities for signs of unauthorized archive uploads
  • Validate integrity of backup archives using cryptographic checksums before restoration
  • Monitor QRadar appliance filesystem for unexpected modifications following backup operations
  • Review and harden QRadar administrative access controls to reduce privileged account attack surface
