40
FAUCET Score

CVE-2012-0183 is a critical memory corruption vulnerability affecting Microsoft Word 2003, 2007, Office for Mac 2008 and 2011, and the Office Compatibility Pack. This "RTF Mismatch Vulnerability" allows remote attackers to execute arbitrary code or cause a denial of service through crafted RTF data. With a CVSS score of 9.3, it is highly severe, requiring no authentication and moderate attack complexity, leading to complete compromise of confidentiality, integrity, and availability. While not listed in CISA KEV, its high EPSS and FAUCET scores, along with media coverage indicating APT use of booby-trapped RTF documents, suggest significant real-world risk, despite no public exploit intelligence.
