Qlik Sense Path Traversal Vulnerability
Qlik Sense contains a path traversal vulnerability that allows a remote, unauthenticated attacker to create an anonymous session by sending maliciously crafted HTTP requests. This anonymous session could allow the attacker to send further requests to unauthorized endpoints.
A remote attacker, without authentication, can achieve full data confidentiality loss, partial data tampering. CISA has confirmed use of this vulnerability in known ransomware campaigns — treat as high priority for remediation. Federal agencies are required to remediate by 2023-12-28 under CISA BOD 22-01.
This is a Path Traversal (CWE-22) vulnerability in Qlik Sense. A path traversal vulnerability found in Qlik Sense Enterprise for Windows for versions May 2023 Patch 3 and earlier, February 2023 Patch 7 and earlier, November 2022 Patch 10 and earlier, and August 2022 Patch 12 and earlier allows an unauthenticated remote attacker to generate an anonymous session. This allows them to transmit HTTP requests to unauthorized endpoints. This is fixed in August 2023 IR, May 2023 Patch 4, February 2023 Patch 8, November 2022 Patch 11, and August 2022 Patch 13. Exploitation requires remote network access, low attack complexity, no authentication required, and no user interaction required.
