CVSS: 8.7EPSS: 0%CPEs: 1EXPL: 0CVE-2024-47874 – Starlette Denial of service (DoS) via multipart/form-data
https://notcve.org/view.php?id=CVE-2024-47874
Starlette is an Asynchronous Server Gateway Interface (ASGI) framework/toolkit. Prior to version 0.40.0, Starlette treats `multipart/form-data` parts without a `filename` as text form fields and buffers those in byte strings with no size limit. This allows an attacker to upload arbitrary large form fields and cause Starlette to both slow down significantly due to excessive memory allocations and copy operations, and also consume more and more memory until the server starts swapping and grinds to a halt, or the OS terminates the server process with an OOM error. Uploading multiple such requests in parallel may be enough to render a service practically unusable, even if reasonable request size limits are enforced by a reverse proxy in front of Starlette. This Denial of service (DoS) vulnerability affects all applications built with Starlette (or FastAPI) accepting form requests. • https://github.com/encode/starlette/security/advisories/GHSA-f96h-pmfr-66vw https://github.com/encode/starlette/commit/fd038f3070c302bff17ef7d173dbb0b007617733 • CWE-770: Allocation of Resources Without Limits or Throttling •

Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading. Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through 3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has only an integer value. Encode.pm, distribuido en Perl versiones hasta 5.34.0, permite a usuarios locales alcanzar privilegios por medio de una biblioteca Encode::ConfigLocal (en el directorio de trabajo actual) que se adelanta a una carga dinámica de módulos. Una explotación requiere una configuración inusual, y determinadas versiones 2021 de Encode.pm (3.05 hasta 3.11). • https://github.com/Perl/perl5/commit/c1a937fef07c061600a0078f4cb53fe9c2136bb9 https://github.com/dankogai/p5-encode/commit/527e482dc70b035d0df4f8c77a00d81f8d775c74 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5NDGQSGMEZ75FJGBKNYC75OTO7TF7XHB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6KOZYD7BH2DNIAEZ2ZL4PJ4QUVQI6Y33 https://metacpan.org/dist/Encode/changes https://news.cpanel.com/unscheduled-tsr-10-august-2021 https://security-tracker.debian.org/tracker • CWE-427: Uncontrolled Search Path Element •
