CVE-2015-1770

Status: AnalyzedHigh (8.8)⚠ Active exploitation

Microsoft Office 2013 SP1 and 2013 RT SP1 allows remote attackers to execute arbitrary code via a crafted Office document, aka "Microsoft Office Uninitialized Memory Use Vulnerability."

CVSS

Exploitation probability (EPSS)

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).

CISA KEV — actively exploited

🎯 ATT&CK techniques
