Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2022-20703 affects Cisco Small Business RV160, RV260, RV340, and RV345 Series Routers; detection should focus on exploitation attempts against these device families including stack-based buffer overflow, unsigned software fetch/execution, and authentication bypass behaviors. ↗
- →Track Cisco bug IDs CSCvz88279, CSCvz94704, CSCwa12732 for patch status and associated firmware versions on RV-series devices; unpatched devices are confirmed exploited in the wild per CISA KEV. ↗
- ·CISA confirmed active exploitation in the wild with a remediation due date of 2022-03-17; any unpatched RV160/RV260/RV340/RV345 device should be treated as potentially compromised. ↗
