CVE-2020-8422: n/a in n/a
An authorization issue was discovered in the Credential Manager feature in Zoho ManageEngine Remote Access Plus before 10.0.450. A user with the Guest role can extract the collection of all defined credentials of remote machines: the credential name, credential type, user name, domain/workgroup name, and description (but not the password).
AI Analysis
Technical Summary
CVE-2020-8422 is a medium-severity authorization vulnerability identified in the Credential Manager feature of Zoho ManageEngine Remote Access Plus versions prior to 10.0.450. The flaw allows a user assigned the Guest role—typically a low-privilege account—to extract sensitive metadata related to stored credentials for remote machines managed by the platform. Specifically, the exposed information includes the credential name, credential type, associated user name, domain or workgroup name, and description. Notably, the actual passwords are not disclosed through this vulnerability. The root cause is an insufficient authorization check that fails to restrict Guest users from accessing the collection of defined credentials. The vulnerability does not require user interaction and can be exploited remotely without authentication complexity beyond possessing a Guest role account. The CVSS v3.0 base score is 4.3, reflecting a low attack complexity, network attack vector, and limited confidentiality impact without affecting integrity or availability. There are no known public exploits in the wild, and no patches or vendor advisories are explicitly linked in the provided data. This vulnerability could be leveraged by an attacker with Guest access to gather credential metadata, which could facilitate further targeted attacks such as social engineering or privilege escalation if combined with other vulnerabilities or misconfigurations.
Potential Impact
For European organizations using Zoho ManageEngine Remote Access Plus, this vulnerability poses a moderate risk primarily related to information disclosure. Although passwords are not exposed, the leakage of credential metadata can aid attackers in mapping the remote access environment, identifying privileged accounts, and crafting more effective attacks. This is particularly concerning for organizations with complex IT infrastructures relying heavily on remote management tools. The exposure of domain/workgroup names and user names could assist in reconnaissance activities, potentially leading to targeted phishing or lateral movement attempts. While the direct impact on confidentiality is limited, the indirect risk of enabling further compromise is significant. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and critical infrastructure, may face compliance and reputational risks if such information is exploited. The vulnerability's exploitation does not require elevated privileges beyond Guest access, which may be easier to obtain in some environments, increasing the threat surface.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should prioritize upgrading Zoho ManageEngine Remote Access Plus to version 10.0.450 or later, where the authorization issue is resolved. In the absence of an immediate patch, organizations should enforce strict access controls by limiting Guest role assignments only to trusted users and regularly auditing user roles and permissions. Network segmentation should be employed to restrict access to the Remote Access Plus interface, especially from untrusted networks. Implementing multi-factor authentication (MFA) for all user roles can reduce the risk of unauthorized Guest account access. Additionally, monitoring and logging access to credential management features can help detect anomalous activities indicative of exploitation attempts. Organizations should also review and minimize the number of stored credentials and ensure that sensitive credential information is encrypted and protected according to best practices. Finally, educating administrators and users about the risks of credential exposure and encouraging prompt reporting of suspicious activities will enhance overall security posture.
