It is noteworthy that in December, ESET had already rectified another vulnerability in its products — CVE-2023-5594 (rated CVSS 7.5), affecting the secure traffic scanning function. Its successful exploitation allowed web browsers to trust websites with certificates signed by obsolete and insecure algorithms.
