CVE-2025-14111 is a path traversal vulnerability identified in the Rarlab RAR App for Android, specifically affecting versions up to 7.11 Build 127. The vulnerability resides in the component com.rarlab.rar, where improper validation of file paths during archive extraction allows an attacker to traverse directories and write files outside the intended extraction folder. This can lead to overwriting or creating files in arbitrary locations on the device's filesystem, potentially compromising data integrity or enabling further malicious actions. The attack vector is remote, but exploitation is complex, requiring user interaction (e.g., opening a crafted archive). The CVSS 4.0 vector indicates network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), user interaction required (UI:P), and low impact on confidentiality, integrity, and availability (each rated low). The vendor has confirmed that this vulnerability affects only the Android version of the RAR app, not the Windows or Unix versions, and has released a fix in version 7.20 Build 128. No known exploits are currently observed in the wild, and the exploitability is considered difficult. The vulnerability's public disclosure emphasizes the need for users to upgrade to the patched version to mitigate risk.

For European organizations, the impact of CVE-2025-14111 is generally low due to the complexity of exploitation and the limited scope of the vulnerability affecting only the Android RAR app. However, organizations that rely heavily on mobile devices for file archiving and extraction, especially those handling sensitive or critical data on Android platforms, could face risks of unauthorized file overwrites or data manipulation. This could lead to localized data integrity issues or facilitate further attacks if malicious files are placed in strategic locations. The vulnerability does not compromise confidentiality directly but can affect integrity and availability at a low level. Given the widespread use of Android devices in Europe, especially in sectors like finance, healthcare, and government, there is a potential for targeted attacks if threat actors craft malicious archives to exploit this flaw. The absence of known exploits in the wild and the availability of a patch reduce the overall risk, but delayed patching could increase exposure.

European organizations should implement the following specific mitigation measures: 1) Immediately upgrade all instances of the Rarlab RAR App on Android devices to version 7.20 Build 128 or later to eliminate the vulnerability. 2) Enforce mobile device management (MDM) policies that restrict installation of outdated or unapproved app versions and enable centralized patch management. 3) Educate users about the risks of opening archive files from untrusted sources, emphasizing caution with unsolicited or suspicious archives. 4) Monitor network traffic and device logs for unusual file extraction activities or attempts to write files outside expected directories. 5) Employ endpoint protection solutions capable of detecting anomalous file system operations on mobile devices. 6) Where possible, limit the use of third-party archiving apps in favor of built-in or vetted alternatives with a strong security track record. 7) Conduct regular security audits of mobile applications and update policies to include rapid response to disclosed vulnerabilities. These steps go beyond generic advice by focusing on organizational controls, user awareness, and proactive patch enforcement tailored to the mobile environment.
