CISA KEV Advisory
Microsoft Office Stack-based Buffer Overflow Vulnerability
A stack-based buffer overflow vulnerability exists in the parsing of RTF data in Microsoft Office and earlier allows an attacker to perform remote code execution.
Apply updates per vendor instructions.
Risk Analysis
This vulnerability in Microsoft Office allows an attacker to execute arbitrary code remotely by sending a specially crafted Rich Text Format (RTF) file. The high EPSS score of 0.93790 indicates a very high likelihood of exploitation, making this a critical vulnerability. Its inclusion in CISA's KEV catalog confirms it has been actively exploited in the past.
Active exploitation of this vulnerability has been observed in the wild, and it is listed in CISA's Known Exploited Vulnerabilities catalog. The nature of the flaw suggests it is remotely exploitable, likely through email or malicious documents.
Users should apply the latest security updates for Microsoft Office to patch this vulnerability. Additionally, exercise caution when opening RTF attachments from untrusted sources.
Technical Analysis
CVE-2010-3333 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2010-3333 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
