Summary
web2py vulnerabilities
Details
It was discovered that web2py does not properly check denied hosts before verifying passwords. An attacker could possibly use this issue to perform brute-force attacks. (CVE-2016-10321)
It was discovered that web2py allows remote attackers to obtain environment variable values. An attacker could possibly use this issue to gain administrative access. (CVE-2016-3952)
It was discovered that web2py uses a hardcoded encryption key. An attacker could possibly use this issue to execute arbitrary code. (CVE-2016-3953, CVE-2016-3954, CVE-2016-3957)

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.
