CVE-2022-40939 is a medium-severity vulnerability affecting multiple versions of Secustation products, specifically versions such as V2.5.5.3116-S50-SMA-B20171107A, V2.3.4.1301-M20-TSA-B20150617A, and several others within the 2.x and 2.5.x release lines. The core issue involves the ability to read the administrator account password, which is a critical security flaw. The vulnerability is categorized under CWE-319, indicating that sensitive information is transmitted or accessible in an insecure manner. The CVSS v3.1 base score is 4.9, with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N. This means the vulnerability can be exploited remotely (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The scope is unchanged (S:U), and the impact is high on confidentiality (C:H), with no impact on integrity (I:N) or availability (A:N). The vulnerability allows an attacker with high privileges to read the administrator password, potentially leading to unauthorized access escalation or lateral movement within the affected environment. No patches or exploits in the wild are currently reported, but the exposure of administrator credentials represents a significant risk if leveraged. The affected products appear to be specialized Secustation devices or software, though the exact product names are not specified. The lack of patch links suggests that remediation may require vendor engagement or configuration changes. Given the nature of the vulnerability, it is likely related to improper storage or transmission of administrator credentials, possibly in plaintext or weakly protected form, enabling privileged users to extract them.

For European organizations using Secustation products, this vulnerability poses a risk primarily to confidentiality. If an attacker or insider with elevated privileges exploits this flaw, they can obtain the administrator password, potentially gaining full administrative control over the affected systems. This could lead to unauthorized access to sensitive data, manipulation of system configurations, and further compromise of networked assets. Critical infrastructure operators, government agencies, and enterprises relying on Secustation devices for security or network management could face increased risk of espionage, data breaches, or operational disruptions. Since the vulnerability does not affect integrity or availability directly, the immediate risk is unauthorized information disclosure. However, possession of administrator credentials could indirectly enable further attacks impacting integrity and availability. The medium CVSS score reflects the requirement for high privileges to exploit, limiting the attack surface to insiders or attackers who have already compromised lower-level accounts. Nonetheless, the potential for privilege escalation and lateral movement makes this a significant concern for organizations with sensitive or regulated data. The absence of known exploits in the wild reduces immediate threat but does not eliminate risk, especially if attackers develop exploit techniques. European organizations should be vigilant, especially those in sectors with high security requirements such as finance, energy, telecommunications, and government.

1. Conduct an immediate inventory to identify all Secustation products and affected versions in use within the organization. 2. Engage with the vendor or authorized support channels to confirm the availability of patches or firmware updates addressing this vulnerability. 3. If patches are unavailable, implement compensating controls such as restricting access to devices to only trusted administrators and monitoring privileged account activities closely. 4. Enforce strict network segmentation to isolate Secustation devices from general user networks, reducing the risk of privilege escalation from compromised endpoints. 5. Employ multi-factor authentication (MFA) for administrative access where supported to mitigate risks from credential exposure. 6. Regularly audit and rotate administrator passwords to limit the window of exposure if credentials are compromised. 7. Monitor logs and network traffic for unusual access patterns or attempts to read sensitive configuration data. 8. Consider deploying host-based intrusion detection systems (HIDS) or endpoint detection and response (EDR) solutions on management workstations to detect exploitation attempts. 9. Educate privileged users about the risks of credential exposure and enforce the principle of least privilege to minimize the number of accounts with high-level access. 10. Prepare incident response plans specifically addressing potential credential compromise scenarios involving Secustation devices.
