Debian DLA-2531-1 : python-bottle security update

medium Nessus Plugin ID 145384

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The package src:python-bottle before 0.12.19 are vulnerable to Web Cache Poisoning by using a vector called parameter cloaking.

When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server.
This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.

For Debian 9 stretch, this problem has been fixed in version 0.12.13-1+deb9u1.

We recommend that you upgrade your python-bottle packages.

For the detailed security status of python-bottle please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/python-bottle

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
