CVE-2023-41266 is a path traversal vulnerability found in Qlik Sense Enterprise for Windows. This vulnerability affects 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. It allows an unauthenticated remote attacker to generate an anonymous session, facilitating the transmission of HTTP requests to unauthorized endpoints. The vulnerability has been addressed in the August 2023 IR, May 2023 Patch 4, February 2023 Patch 8, November 2022 Patch 11, and August 2022 Patch 13.
This vulnerability is classified with a CVSS score of 8.2, indicating a high severity level. Organizations should be aware of the potential risks associated with this vulnerability, as attackers may leverage it to gain unauthorized access to sensitive information. The urgency for defenders is high; organizations should prioritize patching immediately.
Given its exploitability and presence in the Known Exploited Vulnerabilities (KEV) catalog, it is crucial for organizations using affected versions of Qlik Sense to implement the necessary patches to mitigate risks.
The vulnerability was published on August 29, 2023, and has been analyzed thoroughly. Organizations relying on Qlik Sense should actively monitor for updates and apply remediation measures as soon as they become available.
Vulnerability Details
The vulnerability allows an attacker to exploit path traversal weaknesses, which is classified under CWE-22. According to CVSSv3.1, the attack vector is classified as NETWORK, with low complexity and no privileges required. The impact on confidentiality is high, while the integrity impact is low and availability is unaffected.
Technical Analysis
The root cause of this vulnerability lies in improper input validation that allows unauthorized directory access. The attack vector is network-based, which means it can be exploited from a remote location without requiring physical access to the system. The attack complexity is low, making it feasible for attackers to exploit the vulnerability without significant effort.
No user interaction is required for exploitation, meaning that an attacker can exploit the vulnerability without needing any input from a legitimate user. The confidential data could be accessed, leading to potential data breaches. However, the integrity and availability of the system remain unaffected, as the vulnerability primarily focuses on unauthorized access.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive endpoints, potentially leading to data breaches and loss of confidentiality. The blast radius of this vulnerability can be extensive, as it impacts multiple versions of Qlik Sense across various deployments. Organizations should assess their exposure to this vulnerability and implement patching as part of their critical response.
Given the high CVSS score and the presence in the KEV catalog, organizations must address this vulnerability urgently. The EPSS score of 0.942 suggests a very high probability of exploitation if not remediated promptly.
