CVSS: 6.3EPSS: 0%CPEs: 1EXPL: 0CVE-2024-52304 – aiohttp vulnerable to request smuggling due to incorrect parsing of chunk extensions
https://notcve.org/view.php?id=CVE-2024-52304
aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.10.11, the Python parser parses newlines in chunk extensions incorrectly which can lead to request smuggling vulnerabilities under certain conditions. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or `AIOHTTP_NO_EXTENSIONS` is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.10.11 fixes the issue. • https://github.com/aio-libs/aiohttp/commit/259edc369075de63e6f3a4eaade058c62af0df71 https://github.com/aio-libs/aiohttp/security/advisories/GHSA-8495-4g3g-x7pr • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 8.7EPSS: 0%CPEs: 1EXPL: 0CVE-2024-52303 – aiohttp memory leak when middleware is enabled when requesting a resource with a non-allowed method
https://notcve.org/view.php?id=CVE-2024-52303
aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In versions starting with 3.10.6 and prior to 3.10.11, a memory leak can occur when a request produces a MatchInfoError. This was caused by adding an entry to a cache on each request, due to the building of each MatchInfoError producing a unique cache entry. An attacker may be able to exhaust the memory resources of a server by sending a substantial number (100,000s to millions) of such requests. Those who use any middlewares with aiohttp.web should upgrade to version 3.10.11 to receive a patch. • https://github.com/aio-libs/aiohttp/commit/bc15db61615079d1b6327ba42c682f758fa96936 https://github.com/aio-libs/aiohttp/security/advisories/GHSA-27mf-ghqm-j3j8 • CWE-772: Missing Release of Resource after Effective Lifetime •
