CVE-2007-1123 in ZPanel
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in ZPanel 2.0 allow remote attackers to execute arbitrary PHP code via a URL in (1) the body parameter to templates/ZPanelV2/template.php or (2) the page parameter to zpanel.php. NOTE: the zpanel.php vector may overlap CVE-2005-0793.2. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

The vulnerability described in CVE-2007-1123 represents a critical remote code execution flaw within ZPanel 2.0, a web-based control panel system. This issue stems from improper input validation and sanitization mechanisms that fail to properly restrict user-supplied data from being interpreted as executable code. The vulnerability manifests through two distinct attack vectors that exploit the application's handling of user-provided parameters in different script files, creating multiple pathways for malicious actors to gain unauthorized access to the system. The affected components include the templates/ZPanelV2/template.php script and the zpanel.php script, both of which process external input without adequate security controls.
The technical exploitation occurs when attackers manipulate the body parameter in template.php or the page parameter in zpanel.php to inject malicious URLs that point to remote code repositories. This type of vulnerability falls under the CWE-94 category of "Improper Control of Generation of Code" and specifically relates to CWE-434 which addresses "Unrestricted Upload of File with Dangerous Type." The flaw allows remote attackers to include arbitrary PHP files from external sources, effectively bypassing the application's intended security boundaries. The vulnerability is particularly dangerous because it enables attackers to execute arbitrary code on the target system with the privileges of the web server process, potentially leading to complete system compromise. The attack requires minimal privileges and can be executed remotely without authentication, making it highly attractive to malicious actors.
The operational impact of this vulnerability extends beyond simple code execution, as it provides attackers with persistent access to the compromised system. Once exploited, attackers can establish backdoors, escalate privileges, and use the compromised server as a platform for further attacks against other systems. The vulnerability also impacts the integrity and confidentiality of data stored within the ZPanel environment, as attackers can read, modify, or delete sensitive information. Additionally, the presence of this vulnerability may indicate broader security weaknesses in the application's architecture, suggesting potential exposure to other related vulnerabilities. Organizations using ZPanel 2.0 are at significant risk of data breaches, service disruption, and potential regulatory compliance violations.
Mitigation strategies for this vulnerability should focus on immediate patching of the affected ZPanel 2.0 installation, as well as implementing robust input validation mechanisms throughout the application. The recommended approach includes disabling remote file inclusion functionality entirely and implementing strict parameter validation for all user-supplied inputs. Organizations should also consider implementing web application firewalls to detect and block malicious requests targeting these specific parameters. The remediation process should follow established security practices such as those outlined in the OWASP Top Ten and NIST Cybersecurity Framework, ensuring that all input is properly sanitized and validated before processing. Additionally, regular security assessments and vulnerability scanning should be conducted to identify similar issues in other applications and prevent future exploitation attempts. The vulnerability's classification under ATT&CK technique T1190 "Exploit Public-Facing Application" highlights the importance of maintaining up-to-date security controls and monitoring for suspicious network activity.
