Vulnerability from variot - Updated: 2025-04-12 23:30

The Operation and Maintenance Unit (OMU) in Huawei VCN500 with software before V100R002C00SPC200 does not properly invalidate the session ID when an "abnormal exit" occurs, which allows remote attackers to conduct replay attacks via the session ID. Huawei VCN500 is an integrated intelligent video surveillance product from China Huawei. Huawei VCN500 has a replay security vulnerability that allows remote attackers to submit special requests to unauthorized access systems. Huawei VCN500 is prone to a security-bypass vulnerability. Huawei VCN500 V100R002C00SPC200B010 is vulnerable. Operation and Maintenance Unit (OMU) is one of the communication units used to control BSC and monitor the operation of BTS and TC. There is a security vulnerability in the Operation and Maintenance Unit (OMU) of the Huawei VCN500 that uses software versions earlier than V100R002C00SPC200B010. The vulnerability is caused by the fact that the program does not invalidate the session ID when the user logs out abnormally

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.
