CVE-2017-9859 (GCVE-0-2017-9859)
Vulnerability from cvelistv5 – Published: 2017-08-05 17:00 – Updated: 2024-08-05 17:18 Disputed

Summary
An issue was discovered in SMA Solar Technology products. The inverters make use of a weak hashing algorithm to encrypt the password for REGISTER requests. This hashing algorithm can be cracked relatively easily. An attacker will likely be able to crack the password using offline crackers. This cracked password can then be used to register at the SMA servers. NOTE: the vendor's position is that "we consider the probability of the success of such manipulation to be extremely low." Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected

"value": "An issue was discovered in SMA Solar Technology products. The inverters make use of a weak hashing algorithm to encrypt the password for REGISTER requests. This hashing algorithm can be cracked relatively easily. An attacker will likely be able to crack the password using offline crackers. This cracked password can then be used to register at the SMA servers. NOTE: the vendor\u0027s position is that \"we consider the probability of the success of such manipulation to be extremely low.\" Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected"

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.
