VAR-201906-0212

Vulnerability from variot - Updated: 2024-11-23 22:06

An issue was discovered on Linksys WRT1900ACS 1.0.3.187766 devices. A lack of encryption in how the user login cookie (admin-auth) is stored on a victim's computer results in the admin password being discoverable by a local attacker, and usable to gain administrative access to the victim's router. The admin password is stored in base64 cleartext in an "admin-auth" cookie. An attacker sniffing the network at the time of login could acquire the router's admin password. Alternatively, gaining physical access to the victim's computer soon after an administrative login could result in compromise. Linksys WRT1900ACS The device contains cryptographic vulnerabilities.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Linksys WRT1900ACS is a wireless router from Linksys. In Linksys WRT1900ACS version 1.0.3.187766, there is an encryption vulnerability in the storage method of user login key. The vulnerability stems from incorrect use of relevant cryptographic algorithms by network systems or products, resulting in improperly encrypted content, weak encryption, and storing sensitive information in plain text

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.
