CVE-2025-58681 is a Missing Authorization vulnerability (CWE-862) identified in the software product Easy Quotes developed by Jürgen Müller. This vulnerability arises due to incorrectly configured access control security levels, allowing unauthorized users to access certain functionalities or data without proper permission checks. The affected versions include all versions up to 1.2.4, although the exact version range is not fully specified. The vulnerability has a CVSS 3.1 base score of 5.3, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) reveals that the vulnerability can be exploited remotely over the network without any privileges or user interaction, but it only impacts confidentiality to a limited extent, with no impact on integrity or availability. Essentially, an attacker can remotely access certain information or features that should be restricted, potentially exposing sensitive data or internal application details. However, the vulnerability does not allow modification or disruption of the system. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet, suggesting that the vulnerability may be newly disclosed or not yet widely exploited. The root cause is a failure in enforcing proper authorization checks, which is a common security oversight in web or application development, leading to unauthorized data exposure or functionality access.

For European organizations using Easy Quotes, this vulnerability could lead to unauthorized disclosure of sensitive information managed by the application. Although the impact is limited to confidentiality and does not affect integrity or availability, the exposure of internal data could facilitate further attacks or lead to privacy breaches, especially if the application handles personal or business-critical information. Organizations in regulated sectors such as finance, healthcare, or legal services could face compliance risks under GDPR if personal data is exposed. The fact that exploitation requires no authentication and no user interaction increases the risk, as attackers can attempt to exploit the vulnerability remotely without user involvement. However, the medium severity and limited impact suggest that while the threat is real, it is not critical. The absence of known exploits in the wild reduces immediate urgency but does not eliminate the risk of future exploitation. European organizations should be aware of this vulnerability, especially if Easy Quotes is integrated into their workflows or customer-facing services.

Given the lack of an official patch at this time, European organizations should implement compensating controls to mitigate the risk. These include: 1) Conducting a thorough review of access control configurations within Easy Quotes to identify and restrict unauthorized access paths. 2) Applying network-level restrictions such as firewall rules or VPN requirements to limit access to the Easy Quotes application only to trusted internal users or networks. 3) Monitoring application logs for unusual access patterns that could indicate exploitation attempts. 4) Implementing web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting the vulnerable endpoints. 5) Engaging with the vendor or developer to obtain timely patches or updates and planning for rapid deployment once available. 6) Educating internal security teams and users about the vulnerability and encouraging vigilance for suspicious activity. 7) If feasible, isolating the Easy Quotes application environment to reduce exposure. These steps go beyond generic advice by focusing on immediate access control hardening and network segmentation until a formal patch is released.
