CVE-2017-12233: Multiple vulnerabilities in the implementation of the Common Industrial Protocol (CIP) feature in Cisco IOS...

Multiple vulnerabilities in the implementation of the Common Industrial Protocol (CIP) feature in Cisco IOS 12.4 through 15.6 could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerabilities are due to the improper parsing of crafted CIP packets destined to an affected device. An attacker could exploit these vulnerabilities by sending crafted CIP packets to be processed by an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Cisco Bug IDs: CSCuz95334.

Security readout for executives and security teams

This flaw can let a remote, unauthenticated attacker crash an affected Cisco IOS device by sending malformed CIP traffic to it. The business impact is availability loss: network or industrial connectivity can be interrupted if exposed devices reload. CISA lists it as known exploited, so treat internet- or untrusted-network exposure as urgent. Exposure is most likely where Cisco IOS devices in affected versions have the CIP feature enabled and reachable from untrusted networks or OT segments. The bundle does not identify specific hardware models or fixed releases, so asset validation against Cisco guidance is required. Prioritize remediation for exposed or OT-adjacent Cisco IOS devices because the issue is remotely triggerable, unauthenticated, availability-impacting, and listed by CISA as known exploited. Mitigation focus: Identify affected Cisco IOS devices running versions 12.4 through 15.6.; Check Cisco advisory guidance for fixed IOS releases and upgrade paths.; Restrict untrusted access to CIP-reachable management or OT network paths..

Improper Input Validation

Improper Input Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
