CVE-2010-4226: n/a in n/a
cpio, as used in build 2007.05.10, 2010.07.28, and possibly other versions, allows remote attackers to overwrite arbitrary files via a symlink within an RPM package archive.
AI Analysis
Technical Summary
CVE-2010-4226 is a high-severity vulnerability affecting the cpio utility, specifically in versions such as build 2007.05.10, 2010.07.28, and potentially others. The vulnerability arises from cpio's handling of symbolic links within RPM package archives. An attacker can craft a malicious RPM archive containing symlinks that, when extracted using vulnerable versions of cpio, allow overwriting of arbitrary files on the target system. This occurs because cpio does not properly validate or restrict symlink targets during extraction, enabling path traversal and file overwrite attacks. The vulnerability is classified under CWE-59 (Improper Link Resolution Before File Access), indicating a failure to securely handle symbolic links. The CVSS v3.1 base score is 7.2, reflecting a high severity due to the network attack vector, low attack complexity, but requiring high privileges (PR:H) for exploitation, and no user interaction needed. The impact includes full compromise of confidentiality, integrity, and availability of affected systems, as arbitrary files can be overwritten, potentially leading to privilege escalation, system compromise, or denial of service. No known exploits in the wild have been reported, and no official patches are linked in the provided data, suggesting that mitigation may require manual updates or configuration changes. This vulnerability is significant in environments where RPM packages are used and extracted with vulnerable cpio versions, especially in automated build or deployment pipelines that handle untrusted RPMs or where privileged users perform extraction.
Potential Impact
For European organizations, the impact of CVE-2010-4226 can be substantial, particularly in sectors relying on RPM-based Linux distributions such as Red Hat Enterprise Linux, CentOS, or SUSE Linux Enterprise Server, which are widely used across Europe in government, finance, telecommunications, and critical infrastructure. Successful exploitation could allow attackers with network access and elevated privileges to overwrite critical system files, leading to system compromise, data breaches, or service disruptions. This is especially critical for organizations with automated deployment or build systems that process RPM packages, as malicious packages could be introduced either via supply chain attacks or insider threats. The ability to overwrite arbitrary files can facilitate privilege escalation, implant persistent malware, or disrupt services, impacting confidentiality, integrity, and availability of systems and data. Given the high severity and potential for significant operational impact, European organizations must assess their exposure, particularly those in countries with large enterprise Linux deployments and critical infrastructure sectors.
Mitigation Recommendations
To mitigate CVE-2010-4226, European organizations should: 1) Identify and inventory all systems using vulnerable versions of cpio, especially those involved in RPM package extraction. 2) Upgrade cpio to versions where this vulnerability is fixed or use alternative, secure extraction tools that properly validate symlinks within archives. 3) Implement strict controls on RPM package sources, ensuring only trusted and verified packages are used, employing cryptographic signature verification to prevent malicious package introduction. 4) Restrict extraction operations to non-privileged users or sandboxed environments to limit the impact of potential exploitation. 5) Monitor file system integrity on critical systems to detect unauthorized file modifications indicative of exploitation attempts. 6) Incorporate security scanning in build and deployment pipelines to detect malicious or malformed RPM packages. 7) Educate system administrators about the risks of extracting untrusted RPMs and enforce policies to avoid such practices. These targeted measures go beyond generic advice by focusing on controlling the attack vector (RPM package handling), privilege restrictions, and proactive detection.
