CVE-2013-2013 in python-keystoneclient
Summary
by MITRE
The user-password-update command in python-keystoneclient before 0.2.4 accepts the new password in the --password argument, which allows local users to obtain sensitive information by listing the process.

The vulnerability identified as CVE-2013-2013 affects the python-keystoneclient library version 0.2.3 and earlier, representing a critical security flaw in how the user-password-update command handles password arguments. This issue stems from the improper handling of command-line arguments where the new password is passed through the --password flag, creating an exploitable condition that exposes sensitive authentication data. The vulnerability operates at the application level and specifically targets the command-line interface components of the OpenStack Identity service client, which is fundamental to cloud infrastructure authentication management. The flaw enables local attackers to extract password information through process enumeration techniques, fundamentally undermining the security of authentication mechanisms within OpenStack environments.
The technical implementation of this vulnerability involves the insecure passing of sensitive data through command-line arguments without proper sanitization or obfuscation. When users execute the user-password-update command with the --password parameter, the password value becomes visible in the process table accessible to local users through standard system monitoring tools such as ps, top, or similar process inspection utilities. This exposure occurs because command-line arguments are typically stored in memory in plaintext format and remain accessible to processes running with the same privileges as the original user. The vulnerability aligns with CWE-255, which addresses insecure password handling, and specifically relates to CWE-312, concerning exposure of sensitive information through data handling errors. The flaw demonstrates poor input validation and secure coding practices, as the application fails to implement proper argument sanitization or secure memory handling for sensitive data.
The operational impact of CVE-2013-2013 extends beyond simple information disclosure, creating significant risks for cloud infrastructure security and compliance. Local users with access to the system can easily extract authentication credentials, potentially leading to unauthorized access to OpenStack environments and subsequent compromise of cloud resources. This vulnerability directly affects organizations using OpenStack Identity services, where compromised credentials could result in complete system takeover, data breaches, and unauthorized resource consumption. The attack vector is particularly concerning because it requires minimal privileges and can be executed using standard system tools, making it accessible to both casual attackers and malicious insiders. The vulnerability also impacts compliance with security standards such as NIST SP 800-53, which requires protection of sensitive information, and ISO 27001 controls for information security management.
Mitigation strategies for CVE-2013-2013 focus on both immediate remediation and long-term secure coding practices. The primary solution involves upgrading to python-keystoneclient version 0.2.4 or later, where the vulnerability has been addressed through improved argument handling and secure password transmission mechanisms. Organizations should implement additional protective measures including process monitoring to detect unauthorized access attempts, restricting local user privileges where possible, and implementing secure password entry methods such as stdin input instead of command-line arguments. Security configurations should include disabling or restricting access to process inspection tools for non-privileged users, and implementing proper logging and alerting for suspicious activities. The vulnerability also highlights the importance of following ATT&CK framework techniques such as T1059 for command and scripting interpreter usage, and T1070 for indicator removal, as attackers may attempt to cover their tracks after exploiting such vulnerabilities. Organizations should also consider implementing automated patch management systems to ensure timely deployment of security updates and maintain comprehensive inventory of all installed components to prevent similar issues in the future.
