VAR-201407-0231

Vulnerability from variot - Updated: 2023-12-18 12:45

OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules rely exclusively on a time value for entropy in key generation, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by predicting the time of project creation. Supplementary information : CWE Vulnerability type by CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) ( Weak in cryptography PRNG Use of ) Has been identified. OleumTech is a California company that provides wireless remote monitoring equipment for industrial environments. Because the site security key is generated using the time64() function in the standard C library, the attacker exploits the vulnerability to obtain the site security key. Attackers can leverage this weakness to aid in brute-force attacks. Other attacks are also possible. A remote attacker could exploit this vulnerability to compromise password protection by predicting when an item was created

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.
