CVE-2022-43264 is a directory traversal vulnerability affecting Arobas Music's Guitar Pro application for iPad and iPhone versions prior to 1.10.2. This vulnerability allows an unauthenticated attacker to craft a specially designed web request that exploits insufficient input validation in the application's handling of file paths. By manipulating the request, the attacker can traverse directories outside the intended scope and download arbitrary files from the device's file system. The vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), indicating a failure to properly sanitize user-supplied input used in file path operations. The CVSS v3.1 base score is 7.5, reflecting a high severity level due to the vulnerability's network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact is primarily on confidentiality, as attackers can access sensitive files, but it does not affect integrity or availability. There are no known exploits in the wild at the time of publication, and no official patches or vendor advisories are linked in the provided data. The vulnerability affects mobile users running vulnerable versions of Guitar Pro on iOS devices, potentially exposing personal or proprietary data stored on the device or within the app's accessible directories.

For European organizations, especially those in the music, education, or creative industries that utilize Guitar Pro on iOS devices, this vulnerability poses a risk of unauthorized disclosure of sensitive information stored on affected devices. Since the exploit requires no authentication or user interaction, any exposed device connected to untrusted networks could be targeted remotely. The confidentiality breach could lead to leakage of intellectual property, personal user data, or proprietary compositions. While the vulnerability does not directly impact system integrity or availability, the exposure of sensitive files could facilitate further attacks or social engineering campaigns. Organizations with Bring Your Own Device (BYOD) policies or mobile workforce using Guitar Pro on iOS should be particularly cautious. The lack of known exploits reduces immediate risk but does not eliminate the threat, as attackers could develop exploits given the public disclosure.

Organizations should ensure that all iOS devices running Guitar Pro are updated to version 1.10.2 or later, where the vulnerability is addressed. If immediate updating is not feasible, restricting network access to vulnerable devices, especially from untrusted or public networks, can reduce exposure. Employing mobile device management (MDM) solutions to enforce app updates and monitor installed applications is recommended. Additionally, organizations should educate users about the risks of connecting to unsecured Wi-Fi networks and encourage the use of VPNs to protect data in transit. Regular audits of sensitive data stored on mobile devices and limiting the storage of critical files within the app's accessible directories can further mitigate potential data leakage. Monitoring network traffic for unusual requests targeting the app may help detect exploitation attempts. Finally, contacting the vendor for official patches or guidance and staying informed about updates is essential.
