CVSS Base Vector:
The remote host is missing an update for the 'python2.7'
Linux Distribution Package(s) announced via the DLA-2628-1 advisory.
Checks if a vulnerable Linux Distribution Package version is present on the target host.
Two security issues have been discovered in python2.7:
The documentation XML-RPC server in Python 2.7 has XSS via the server_title
field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in
Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with
visit the http URL for this server.
The Python2.7 vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl
and urllib.parse.parse_qs 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.
Please be sure your software is working properly if it uses `urllib.parse.parse_qs`
or `urllib.parse.parse_qsl`, `cgi.parse` or `cgi.parse_multipart`.
Earlier Python versions allowed using both semicolon and ``&`` as query parameter
separators in `urllib.parse.parse_qs` and `urllib.parse.parse_qsl`.
Due to security concerns, and to conform with
newer W3C recommendations, this has been changed to allow only a single
separator key, with ``&`` as the default. This change also affects
`cgi.parse` and `cgi.parse_multipart` as they use the affected
functions internally. For more details, please see their respective
'python2.7' Linux Distribution Package(s) on Debian Linux.
For Debian 9 stretch, these problems have been fixed in version
We recommend that you upgrade your python2.7 Linux Distribution Packages.
