SCA: security update for slim/psr7 (GHSA-q2qj-628g-vhfw)
medium Tenable Cloud Security Plugin ID 417813
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- slim/psr7 is a PSR-7 implementation for use with Slim 4. In versions prior to 1.6.1 an attacker could
sneak in a newline (\n) into both the header names and values. While the specification states that
\r\n\r\n is used to terminate the header list, many servers in the wild will also accept \n\n. An attacker
that is able to control the header names that are passed to Slilm-Psr7 would be able to intentionally
craft invalid messages, possibly causing application errors or invalid HTTP requests being sent out with
an PSR-18 HTTP client. The latter might present a denial of service vector if a remote service’s web
application firewall bans the application due to the receipt of malformed requests. The issue has been
patched in version 1.6.1. There are no known workarounds to this issue. Users are advised to upgrade.
