CVE-2017-12233
In short
Cisco IOS devices with CIP support can crash when receiving specially crafted packets, leaving the network device unavailable. An attacker on the internet can trigger this remotely without needing credentials.
Technical detail
Multiple parsing flaws in the Common Industrial Protocol (CIP) implementation in Cisco IOS 12.4–15.6 allow unauthenticated remote attackers to send malformed CIP packets that cause the device to reload. The vulnerability requires only network reachability to the affected device and results in denial of service via device crash.
Summary generated and translated by AI from the official description.
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.
