JetBrains IntelliJ IDEA vulnerability analysis and mitigation

A path traversal vulnerability was discovered in JetBrains IntelliJ IDEA's built-in web server, affecting versions before 2022.3. The vulnerability, identified as CVE-2022-46826, was disclosed on December 8, 2022, and allows unauthorized access to arbitrary files through path traversal exploitation (NVD Database, CVE Mitre).

The vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) and CWE-35 (Path Traversal). It received a CVSS v3.1 base score of 5.5 (Medium) from NIST with a vector string of CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, while JetBrains assessed it with a slightly higher score of 6.2 (Medium) with vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N (NVD Database).

The vulnerability allows an attacker to read arbitrary files on the system through the built-in web server, potentially exposing sensitive information. The high confidentiality impact (C:H) in the CVSS score indicates significant potential for unauthorized information disclosure (NVD Database).

The vulnerability was addressed in JetBrains IntelliJ IDEA version 2022.3. Users are advised to upgrade to this version or later to mitigate the risk (JetBrains Advisory).
