FAUCET Score

CVE-2022-3377 is a critical vulnerability affecting Horner Automation's Cscape software, versions 9.90 SP 6 and earlier. It stems from improper validation of user-supplied data, specifically when processing maliciously crafted FNT files. This flaw allows an attacker to execute arbitrary code within the current process by exploiting an uninitialized pointer, leading to an out-of-bounds memory read. Rated with a CVSS score of 7.8 (HIGH), the vulnerability requires user interaction (UI:R) and local access (AV:L), but has low attack complexity (AC:L). Successful exploitation could result in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H). Currently, there is no evidence of active exploitation, nor is public exploit code available in Metasploit, Nuclei, or ExploitDB. The vulnerability has also received minimal community discussion and media coverage, indicating a low level of public awareness and attention.
