Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2020-1102 is exploited by uploading a specially crafted SharePoint application package; monitor SharePoint for unexpected or unauthorized application package uploads. ↗
- →Successful exploitation results in code execution under the SharePoint application pool identity and SharePoint server farm account; monitor for anomalous process activity spawned from SharePoint worker processes (w3wp.exe). ↗
- →CVE-2020-1102 is one of three SharePoint RCEs (alongside CVE-2020-1023, CVE-2020-1024, CVE-2020-1069) triggered via malicious application package upload; correlate SharePoint app-package upload events across all four CVEs. ↗
- ·The vulnerability exists specifically in how SharePoint checks the source markup of application packages; the fix corrects this markup validation logic. ↗
- ·As of the advisory publication, CVE-2020-1102 had not been publicly disclosed or actively exploited in the wild, reducing immediate urgency but not eliminating risk. ↗
