Vulnerability from variot - Updated: 2025-04-13 20:28

Memory leak in the TCP input module in Cisco IOS 12.2, 12.4, 15.0, 15.2, 15.3, and 15.4 and IOS XE 3.3.xXO, 3.5.xE, 3.6.xE, 3.8.xS through 3.10.xS before 3.10.5S, and 3.11.xS and 3.12.xS before 3.12.3S allows remote attackers to cause a denial of service (memory consumption or device reload) by sending crafted TCP packets over (1) IPv4 or (2) IPv6, aka Bug ID CSCum94811. Cisco IOS is a popular Internet operating system. Cisco IOS and IOS XE Software are prone to a remote denial-of-service vulnerability. Successful exploits may allow attackers to cause a memory leak and reload of an affected device, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCum94811. The vulnerability stems from the fact that the program does not properly handle the packet sequence used for the TCP three-way handshake. The following products and versions are affected: Cisco IOS Releases 12.2, 12.4, 15.0, 15.2, 15.3, 15.4 and IOS XE 3.3.xXO, 3.5.xE, 3.6.xE, 3.8.xS through 3.10 .xS version, 3.11.xS version, 3.12.xS version before 3.12.3S

    "data": "Memory leak in the TCP input module in Cisco IOS 12.2, 12.4, 15.0, 15.2, 15.3, and 15.4 and IOS XE 3.3.xXO, 3.5.xE, 3.6.xE, 3.8.xS through 3.10.xS before 3.10.5S, and 3.11.xS and 3.12.xS before 3.12.3S allows remote attackers to cause a denial of service (memory consumption or device reload) by sending crafted TCP packets over (1) IPv4 or (2) IPv6, aka Bug ID CSCum94811. Cisco IOS is a popular Internet operating system. Cisco IOS and IOS XE Software are prone to a remote denial-of-service vulnerability. \nSuccessful exploits may allow attackers to cause a memory leak and reload of an affected device, denying service to legitimate users. \nThis issue is being tracked by Cisco Bug ID CSCum94811. The vulnerability stems from the fact that the program does not properly handle the packet sequence used for the TCP three-way handshake. The following products and versions are affected: Cisco IOS Releases 12.2, 12.4, 15.0, 15.2, 15.3, 15.4 and IOS XE 3.3.xXO, 3.5.xE, 3.6.xE, 3.8.xS through 3.10 .xS version, 3.11.xS version, 3.12.xS version before 3.12.3S",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
