CVE-2008-3477
Status: ModifiedHigh (9.3)—
Microsoft Excel 2000 SP3, 2002 SP3, and 2003 SP2 and SP3 does not properly validate data in the VBA Performance Cache when processing an Office document with an embedded object, which allows remote attackers to execute arbitrary code via an Excel file containing a crafted value, leading to heap-based buffer overflows, integer overflows, array index errors, and memory corruption, aka "Calendar Object Validation Vulnerability."
CVSS
- Version: 2.0
- Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
- Base score: 9.3
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 36%
- Percentile among all scored CVEs: 98
- Score date: 10/9/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
