OESA-2023-1900 (CVE-2023-49081)

Vulnerability from osv_openeuler – Published: 2023-12-08 11:06 – Updated: 2026-08-06 11:06 – Source website

Summary

python-aiohttp security update

Details

Async http client/server framework (asyncio).

Security Fix(es):

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Improper validation made it possible for an attacker to modify the HTTP request (e.g. to insert a new header) or create a new HTTP request if the attacker controls the HTTP version. The vulnerability only occurs if the attacker can control the HTTP version of the request. This issue has been patched in version 3.9.0.(CVE-2023-49081)

Severity

7.2 (High)

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.
