It is suggested to upgrade the affected component.

Detailsinfo

A vulnerability classified as critical has been found in OpenSSL up to 3.0.6 (Network Encryption Software). This affects an unknown code of the component X.509 Certificate Handler. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability.

The weakness was presented 11/01/2022. It is possible to read the advisory at openssl.org. This vulnerability is uniquely identified as CVE-2022-3602. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Colm MacCárthaigh (colmmacc) in Python and been published immediately after the advisory. The exploit is shared for download at github.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 209848 (Fortinet Fortigate OpenSSL3 CVE-2022-3602 CVE-2022-3786 vulnerabilities (FG-IR-22-419)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 3.0.7 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (209848). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
