Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-3688-1)
Summary:	The remote host is missing an update for the Debian 'haproxy' package(s) announced via the DLA-3688-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'haproxy' package(s) announced via the DLA-3688-1 advisory. Vulnerability Insight: It was discovered that there was a potential information disclosure vulnerability in HAProxy, a reverse proxy server used to load balance HTTP requests across multiple servers. HAProxy formerly accepted the # (ie. the 'pound' or 'hash') symbol as part of a URI component. This might have allowed remote attackers to obtain sensitive information upon HAProxy's misinterpretation of a path_end rule, such as by routing index.html#.png to a static server. CVE-2023-45539 HAProxy before 2.8.2 accepts # as part of the URI component, which might allow remote attackers to obtain sensitive information or have unspecified other impact upon misinterpretation of a path_end rule, such as routing index.html#.png to a static server. For Debian 10 Buster, this problem has been fixed in version 1.8.19-1+deb10u5. We recommend that you upgrade your haproxy packages.

Solution: Please install the updated package(s). CVSS Score: 8.5 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:P/A:N
