CVE-2022-41712 is a path traversal vulnerability identified in Frappe version 14.10.0. Frappe is a full-stack web application framework commonly used for building ERP and business applications. The vulnerability arises due to improper validation of user-supplied input in the 'import_file' parameter. Specifically, the application fails to sanitize or restrict the file path input, allowing an attacker to manipulate the path and access arbitrary local files on the server. This type of vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). Exploitation requires the attacker to have low privileges (PR:L) but does not require user interaction (UI:N) and can be performed remotely over the network (AV:N). The CVSS v3.1 base score is 6.5, indicating a medium severity level. The impact primarily affects confidentiality, as an attacker can read sensitive files, but does not affect integrity or availability. No known exploits are currently reported in the wild, and no official patches or vendor advisories are linked. The vulnerability is significant because it can expose sensitive configuration files, credentials, or other critical data stored on the server, potentially leading to further compromise if leveraged in a multi-stage attack. Given that Frappe is often deployed in enterprise environments for business-critical applications, this vulnerability poses a risk to data confidentiality and privacy.

For European organizations using Frappe 14.10.0, this vulnerability could lead to unauthorized disclosure of sensitive internal files, including configuration files, database credentials, or proprietary business data. This exposure can result in data breaches, regulatory non-compliance (e.g., GDPR violations), and loss of customer trust. Since Frappe is used in ERP and business management systems, the confidentiality breach could disrupt business operations indirectly by enabling attackers to gather intelligence for further attacks such as privilege escalation or lateral movement. Although the vulnerability does not directly affect system integrity or availability, the confidentiality impact alone is significant, especially for organizations handling personal data or critical infrastructure information. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits over time. European organizations in sectors like manufacturing, finance, healthcare, and public administration that rely on Frappe-based solutions are particularly at risk. Additionally, failure to address this vulnerability could lead to reputational damage and potential legal consequences under European data protection laws.

1. Immediate mitigation should involve upgrading Frappe to a version where this vulnerability is fixed; if no official patch exists, organizations should apply custom input validation to sanitize and restrict the 'import_file' parameter to prevent path traversal sequences such as '../'. 2. Implement strict allowlisting of file paths and names that can be accessed via the import functionality, ensuring only intended files are accessible. 3. Employ web application firewalls (WAFs) with rules designed to detect and block path traversal attempts targeting the 'import_file' parameter. 4. Conduct thorough code reviews and penetration testing focused on file handling and input validation mechanisms within Frappe deployments. 5. Monitor application logs for suspicious access patterns or attempts to access unauthorized files. 6. Restrict file system permissions so that the application process has minimal access rights, limiting the impact of any file disclosure. 7. Educate developers and administrators about secure coding practices related to file input handling to prevent similar vulnerabilities. 8. If upgrading is delayed, consider disabling or restricting the import functionality temporarily to reduce exposure.
