⚡ RCE ⌖ EXPLOITED IN THE WILD SHAME 85/100 rceexploited-in-wildunpatchedsupply-chaindata-breachnegligence

Cisco IOS and IOS XE Smart Install allows unauthenticated remote attackers to execute code, causing device reloads, DoS, or full compromise.

Cisco IOS and IOS XE improperly validates packet data in the Smart Install feature, enabling unauthenticated remote code execution, denial-of-service, or device reloads. DIB organizations must treat this as a critical supply-chain and infrastructure risk, as compromised network devices can be used as pivots for lateral movement or data exfiltration. Immediate patching and strict network segmentation are required to mitigate exploitation.

Shame score — A foundational networking OS with persistent RCE flaws that are actively exploited in the wild, indicating systemic negligence in input validation and patching.

▸ RECOMMENDED ACTION  Actively exploited (CISA KEV) — remediate now, ahead of your normal patch cycle.

DESCRIPTION

Cisco IOS and IOS XE Software improperly validates packet data, allowing an unauthenticated, remote attacker to trigger a reload of an affected device, cause a denial-of-service (DoS) condition, or perform code execution on the affected device.
