CVE-2007-2660 in CJG EXPLORER PRO
Summary
by MITRE
** DISPUTED ** PHP remote file inclusion vulnerability in pcltrace.lib.php in the PclTar module in Vincent Blavet PhpConcept Library, as used in CJG EXPLORER PRO 3.3 and earlier and probably other products, allows remote attackers to execute arbitrary PHP code via a URL in the g_pcltar_lib_dir parameter. NOTE: CVE disputes this issue since there is no include statement in pcltrace.lib.php. NOTE: the pcltar.lib.php vector is already covered by CVE-2007-2199.

The vulnerability identified as CVE-2007-2660 relates to a potential remote file inclusion flaw within the PclTar module of Vincent Blavet PhpConcept Library, which was reportedly present in CJG EXPLORER PRO 3.3 and earlier versions. This issue specifically targeted the pcltrace.lib.php file, which was part of the broader PclTar functionality. The vulnerability was classified as disputed by the CVE organization due to the absence of explicit include or require statements within the affected pcltrace.lib.php file, which would typically be necessary for remote file inclusion attacks to succeed. However, the vulnerability was noted to be related to a similar issue covered under CVE-2007-2199, indicating that the broader PclTar module was indeed susceptible to remote code execution through file inclusion mechanisms. The technical nature of this vulnerability aligns with CWE-88, which describes improper neutralization of special elements used in an OS command, and more specifically with CWE-94, which addresses the execution of arbitrary code or commands, particularly in contexts involving dynamic code execution or file inclusion.
The operational impact of this vulnerability, if exploitable, would have allowed remote attackers to execute arbitrary PHP code on affected systems. The attack vector involved manipulation of the g_pcltar_lib_dir parameter through a URL, which would then be processed by the vulnerable code. This type of vulnerability represents a significant security risk, as it could enable attackers to gain unauthorized access to systems, execute malicious code, and potentially establish persistent access. The nature of PHP remote file inclusion vulnerabilities typically allows attackers to include malicious files from remote servers, which then get executed on the target system. This vulnerability would have been particularly concerning in web applications where user input is not properly sanitized, as it could be exploited through parameters passed to the application. The ATT&CK framework would categorize this under T1059.007 for execution through PHP, and potentially T1190 for exploitation of remote file inclusion vulnerabilities.
The disputed nature of this CVE highlights the complexity of vulnerability assessment and the importance of thorough code analysis. While the specific pcltrace.lib.php file did not contain include statements, the vulnerability was recognized as part of a broader pattern affecting the PclTar module. This underscores the need for comprehensive security reviews of entire libraries rather than isolated files. The fact that this vulnerability overlaps with CVE-2007-2199 demonstrates how similar issues within the same software ecosystem can be categorized differently but represent related security concerns. Organizations using affected versions of CJG EXPLORER PRO or other products utilizing the PhpConcept Library should have implemented proper input validation and sanitization measures. The recommended mitigations would have included upgrading to patched versions of the software, implementing proper parameter validation, and ensuring that file inclusion operations do not accept user-controllable input without adequate sanitization. Additionally, the use of secure coding practices such as whitelisting allowed file paths and avoiding dynamic include operations would have provided effective protection against similar vulnerabilities. The vulnerability also emphasizes the importance of maintaining up-to-date software libraries and conducting regular security assessments to identify and remediate potential attack vectors in web applications.
