Details

OISF suricata-update unsafely deserializes YAML data Suricata-Update uses the insecure `yaml.load()` function. Code will be executed if the yaml-file contains lines like: ```yaml hello: !!python/object/apply:os.system ['ls -l > /tmp/output'] ``` The vulnerable function can be triggered by "suricata-update list-sources". The locally stored index.yaml will be loaded in this function and the malicious code gets executed.
