CVE-2025-58740 is a vulnerability classified under CWE-321, indicating the use of a hard-coded cryptographic key within the Milner ImageDirector Capture software, specifically in the C2SGlobalSettings.dll component on Windows platforms. The affected versions range from 7.0.9 up to but not including 7.6.3.25808. The vulnerability arises because the cryptographic key used in the Password function is embedded directly in the executable, allowing a local attacker with read access to the binary to extract this key. Once obtained, the attacker can decrypt database credentials stored or managed by the application, compromising sensitive authentication material. The vulnerability requires local access with low privileges (PR:L) but does not require user interaction (UI:N) or additional authentication (AT:N). The CVSS 4.0 base score is 8.5, reflecting high severity due to the high impact on confidentiality (VC:H) and availability (VA:H), with limited integrity impact (VI:L). The scope is high (S:H), indicating that exploitation could affect resources beyond the initially vulnerable component. Although no public exploits are known, the presence of hard-coded keys is a critical security flaw that can facilitate privilege escalation or lateral movement within a compromised network. The vulnerability affects organizations using Milner ImageDirector Capture for image and document capture workflows, potentially exposing sensitive database credentials that could be leveraged to access backend systems or data stores.

For European organizations, the impact of CVE-2025-58740 can be significant, especially in sectors relying on document imaging and capture solutions such as healthcare, legal, finance, and government agencies. The compromise of database credentials could lead to unauthorized access to sensitive data repositories, undermining confidentiality and potentially causing data breaches. This could result in regulatory non-compliance with GDPR and other data protection laws, leading to legal and financial penalties. Additionally, attackers gaining access through decrypted credentials might move laterally within networks, escalating privileges or disrupting operations, impacting availability. The vulnerability's requirement for local access limits remote exploitation but raises concerns for insider threats or attackers who have already gained foothold in the network. Organizations with distributed imaging infrastructure or remote offices may face challenges in securing all endpoints. The high severity score underscores the urgency to address this vulnerability to prevent potential exploitation and data compromise.

1. Apply official patches or updates from Milner as soon as they become available to remove the hard-coded key and implement secure key management practices. 2. Until patches are released, restrict local access to systems running ImageDirector Capture by enforcing strict access controls, limiting user permissions, and using endpoint security solutions to monitor and block unauthorized file access. 3. Employ application whitelisting and integrity monitoring on the C2SGlobalSettings.dll and related binaries to detect unauthorized modifications or attempts to extract embedded keys. 4. Rotate database credentials regularly and implement multi-factor authentication for database access to reduce the risk posed by compromised credentials. 5. Monitor logs and network traffic for unusual access patterns or attempts to use decrypted credentials to access backend systems. 6. Conduct internal audits and penetration tests focusing on local privilege escalation vectors to identify and remediate similar weaknesses. 7. Educate staff about the risks of local privilege misuse and enforce policies to minimize insider threats.
