Debian · Bcfg2 · CVE-2011-3211
**Name of the Vulnerable Software and Affected Versions**
Bcfg2 versions 1.1.2 and earlier
Bcfg2 version 1.2 prerelease
**Description**
The issue allows remote attackers to execute arbitrary commands via shell metacharacters in data received from a client. Multiple vulnerabilities in the Bcfg2 package of the Debian GNU/Linux operating system can be exploited remotely, potentially leading to a breach of confidentiality, integrity, and availability of protected information.
**Recommendations**
For Bcfg2 versions 1.1.2 and earlier, consider disabling the reception of client data until a patch is available.
For Bcfg2 version 1.2 prerelease, restrict access to the server to minimize the risk of exploitation.
As a temporary workaround, consider validating and sanitizing all client data to prevent the execution of arbitrary commands via shell metacharacters.
