CVE-2023-31038

8.8 · HIGH

SQL injection in Log4cxx when using the ODBC appender to send log messages to a database.

Published May 8, 2023CWE-89EPSS 1.60%

Overview

CVE-2023-31038 is a high-severity vulnerability. It was published on May 8, 2023 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

SQL injection in Log4cxx when using the ODBC appender to send log messages to a database.  No fields sent to the database were properly escaped for SQL injection.  This has been the case since at least version 0.9.0(released 2003-08-06)

Note that Log4cxx is a C++ framework, so only C++ applications are affected.

Before version 1.1.0, the ODBC appender was automatically part of Log4cxx if the library was found when compiling the library.  As of version 1.1.0, this must be both explicitly enabled in order to be compiled in.

Three preconditions must be met for this vulnerability to be possible:

1. Log4cxx compiled with ODBC support(before version 1.1.0, this was auto-detected at compile time)

2. ODBCAppender enabled for logging messages to, generally done via a config file

3. User input is logged at some point. If your application does not have user input, it is unlikely to be affected.

Users are recommended to upgrade to version 1.1.0 which properly binds the parameters

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
