CVE-2025-5100 is a high-severity vulnerability identified in the Mobile Dynamix PrinterShare Mobile Print application, specifically version 12.15.01. The vulnerability arises from a double-free condition occurring during the cleanup process of temporary image files. A double-free vulnerability happens when a program attempts to free the same memory location twice, which can corrupt the memory management data structures. This corruption can lead to undefined behavior, including memory corruption, crashes, or potentially arbitrary code execution. In this case, the vulnerability allows an attacker to exploit the double-free flaw to achieve memory corruption, which could be leveraged to execute arbitrary code on the affected device. The CVSS v3.1 base score is 8.0, indicating a high severity level. The vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L) shows that the attack vector requires local access (AV:L), has low attack complexity (AC:L), requires no privileges (PR:N), and no user interaction (UI:N). The scope is unchanged (S:U), and the impact on confidentiality and integrity is high (C:H/I:H), with a low impact on availability (A:L). No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability is related to CWE-415 (Double Free) and CWE-416 (Use After Free), both of which are common memory corruption issues that can lead to severe security consequences if exploited. The flaw specifically affects the cleanup routine of temporary image files, which suggests that the vulnerability could be triggered by manipulating print jobs or image files processed by the application. Since PrinterShare Mobile Print is a mobile printing solution, the affected devices are likely smartphones or tablets running the vulnerable version of the app. Exploitation could allow attackers to execute arbitrary code locally, potentially leading to privilege escalation or further compromise of the device.

For European organizations, this vulnerability poses a significant risk, especially for those relying on mobile printing solutions in their operational workflows. The ability to execute arbitrary code locally on devices used within corporate environments could lead to unauthorized access to sensitive documents, lateral movement within internal networks, or deployment of malware. Confidentiality and integrity of printed documents and related data could be compromised. The low requirement for privileges and no need for user interaction increases the risk of exploitation by insiders or through compromised devices. Organizations with mobile workforces or those using PrinterShare Mobile Print in regulated sectors such as finance, healthcare, or government could face compliance and data protection challenges if this vulnerability is exploited. Additionally, the potential for memory corruption could cause application crashes or device instability, impacting availability of printing services and productivity.

Given the absence of an official patch at this time, European organizations should implement several practical mitigations: 1) Restrict installation and use of PrinterShare Mobile Print version 12.15.01 on corporate mobile devices until a patch is available. 2) Employ mobile device management (MDM) solutions to enforce application version controls and prevent installation of vulnerable versions. 3) Limit local access to devices by enforcing strong physical security and endpoint access controls to reduce the risk of local exploitation. 4) Monitor device logs and application behavior for signs of memory corruption or abnormal crashes related to printing activities. 5) Educate users about the risks of using untrusted print jobs or image files that could trigger the vulnerability. 6) Once a patch is released, prioritize immediate deployment across all affected devices. 7) Consider alternative secure printing solutions with better security track records until this vulnerability is resolved. 8) Implement network segmentation to isolate mobile devices from critical infrastructure to limit potential lateral movement if exploitation occurs.
