PyMongo < 4.6.3 Out-of-bounds Read

medium Nessus Plugin ID 193202

Language:

Synopsis

A Python library installed on the remote host is affected by a vulnerability.

Description

Versions of the package pymongo before 4.6.3 are vulnerable to Out-of-bounds Read in the bson module. Using the crafted payload the attacker could force the parser to deserialize unmanaged memory. The parser tries to interpret bytes next to buffer and throws an exception with string. If the following bytes are not printable UTF-8 the parser throws an exception with a single byte.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PyMongo or PyMongox version 4.6.3 or later.
