CVE-2025-7703 is an authentication vulnerability identified in the TECNO mobile application tech.palm.id, specifically affecting version 2.5.0.65. The weakness is classified under CWE-287, which pertains to improper authentication mechanisms. This vulnerability allows an attacker to bypass or weaken the authentication process, potentially leading to unauthorized access to certain application features or data. Although the CVSS v3.1 base score is 3.1, indicating a low severity, the vulnerability still poses a risk of information leakage. The attack vector is network-based (AV:N), requiring low privileges (PR:L) but no user interaction (UI:N). The attack complexity is high (AC:H), meaning exploitation is not straightforward and requires specific conditions or knowledge. The scope is unchanged (S:U), and the impact is limited to confidentiality (C:L) with no impact on integrity or availability. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability could allow an attacker with some level of access to the network to gain unauthorized information from the application due to insufficient authentication controls, potentially exposing sensitive user data or application information.

For European organizations, the impact of this vulnerability depends largely on the adoption and use of the TECNO tech.palm.id application within their operations or user base. If used internally or by customers, the improper authentication could lead to unauthorized information disclosure, which may include personal data or sensitive business information. This could result in privacy violations under GDPR, reputational damage, and potential regulatory fines. However, given the low CVSS score and the high attack complexity, the immediate risk is limited. The vulnerability does not affect data integrity or availability, reducing the risk of service disruption or data manipulation. Nonetheless, organizations should consider this vulnerability in their risk assessments, especially if the app handles sensitive or regulated data. Attackers with network access and some privileges could exploit this flaw to gather information that might facilitate further attacks or social engineering campaigns.

To mitigate this vulnerability, European organizations using the tech.palm.id application should: 1) Monitor for updates from TECNO and apply patches promptly once available. 2) Restrict network access to the application backend, employing network segmentation and firewall rules to limit exposure to trusted users and devices only. 3) Implement additional authentication layers or multi-factor authentication (MFA) where possible to compensate for the app's weak authentication. 4) Conduct regular security assessments and penetration testing focused on authentication mechanisms within the app environment. 5) Educate users about the risks of unauthorized access and encourage vigilance for suspicious activity. 6) Log and monitor authentication attempts and access patterns to detect potential exploitation attempts early. 7) If feasible, consider alternative applications with stronger authentication controls until a fix is available.
