CVE-2023-26441 Explained : Impact and Mitigation

This CVE record was published on August 2, 2023, with an update on January 12, 2024. The vulnerability affects OX App Suite versions up to 8.10, and it involves a security issue related to the Cacheservice component.

Understanding CVE-2023-26441

This section delves into the specifics of CVE-2023-26441, shedding light on the vulnerability's nature and impact.

What is CVE-2023-26441?

The Cacheservice within OX App Suite failed to properly verify relative cache objects' paths when accessing resources. This oversight could allow an attacker with access to the database and a local or restricted network to read arbitrary local file system resources accessible by the service's system user account. The recent updates have addressed this flaw by enhancing path validation to restrict access to the defined root directory.

The Impact of CVE-2023-26441

While the vulnerability has a base severity rating of "MEDIUM" with a CVSSv3.1 score of 5.7, it poses a high risk to confidentiality. If exploited, an attacker could potentially access sensitive information on the local file system, compromising data security.
