CVE-2024-6648 is a high-severity Absolute Path Traversal vulnerability affecting Apollo Theme's AP Page Builder versions prior to 4.0.0. This vulnerability arises from improper limitation of a pathname to a restricted directory (CWE-22). Specifically, it allows an unauthenticated remote attacker to manipulate the 'product_item_path' parameter within the 'config' JSON file. By exploiting this flaw, the attacker can read arbitrary files on the underlying system, bypassing intended access controls. The vulnerability does not require any authentication or user interaction, and can be triggered remotely over the network. The CVSS 4.0 base score of 8.7 reflects the ease of exploitation (no privileges or user interaction needed) and the high impact on confidentiality, as sensitive files can be exposed. The vulnerability does not affect integrity or availability directly but poses a significant risk of information disclosure, which could lead to further attacks such as credential theft or system reconnaissance. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and thus may attract attackers. The lack of an official patch at the time of reporting increases the urgency for mitigation.

For European organizations using AP Page Builder, this vulnerability poses a serious risk of unauthorized disclosure of sensitive information, including configuration files, credentials, or other critical data stored on the server. Such data exposure can facilitate lateral movement, privilege escalation, or targeted attacks against the organization. Industries with stringent data protection requirements, such as finance, healthcare, and government, are particularly vulnerable to compliance violations and reputational damage if exploited. Since the vulnerability allows unauthenticated remote access, attackers can scan and exploit vulnerable instances en masse, increasing the likelihood of widespread compromise. The impact is heightened in multi-tenant or shared hosting environments where one compromised instance could lead to broader exposure. Additionally, the exposure of internal files may reveal further vulnerabilities or system details that attackers can leverage.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include restricting network access to the AP Page Builder interface using firewalls or VPNs to limit exposure to trusted users only. Web application firewalls (WAFs) should be configured to detect and block suspicious requests attempting path traversal patterns, such as those containing '../' sequences or attempts to access sensitive file paths. Organizations should audit and harden file system permissions to ensure that the web server process has minimal read access, limiting the impact of any file disclosure. Monitoring and logging access to the 'config' JSON file and related resources can help detect exploitation attempts. It is also advisable to isolate AP Page Builder instances from critical infrastructure and sensitive data stores. Once a patch becomes available, prompt application of the update is essential. Finally, organizations should conduct vulnerability scans and penetration tests to identify any exposed instances and verify the effectiveness of mitigations.
