Details

A security flaw has been discovered in opensource-socialnetwork up to 9.11/10.1. This affects the function input of the file actions/administrator/cache/dynamic.php of the component Cache Settings. Performing a manipulation of the argument host/port/username/password/type/status results in code injection. The attack can be initiated remotely.

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.
