VAR-201001-0762

Vulnerability from variot - Updated: 2025-04-11 23:10

Unspecified vulnerability in the sshd_child_handler process in the SSH server in Cisco IOS XR 3.4.1 through 3.7.0 allows remote attackers to cause a denial of service (process crash and memory consumption) via a crafted SSH2 packet, aka Bug ID CSCsu10574. An attacker can exploit this issue to cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCsu10574. CVE ID: CVE-2010-0137 Cisco IOS XR Software is a set of completely modularized and distributed network operating systems in Cisco's IOS software series (including IOS T, IOS S and IOS XR). A large amount of memory is exhausted during this event, and repeated attacks may affect other system functions, depending on the amount of available memory and the duration of the attack. Although user authentication is not required to exploit this vulnerability, the TCP triple handshake must be completed and some SSH protocol negotiations must occur. The SSH service continued to function normally after the attack.

Please see the vendor's advisory for a complete list of affected versions.

SOLUTION: Update to fixed versions. Please see the vendor's advisory for details.

PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

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.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
