CVE-2024-42192: CWE-522 Insufficiently Protected Credentials in HCL Software Traveler for Microsoft Outlook
HCL Traveler for Microsoft Outlook (HTMO) is susceptible to a credential leakage which could allow an attacker to access other computers or applications.
AI Analysis
Technical Summary
CVE-2024-42192 identifies a vulnerability in HCL Traveler for Microsoft Outlook (HTMO) version 3.0.14, categorized under CWE-522: Insufficiently Protected Credentials. This vulnerability arises because the software does not adequately safeguard stored credentials, potentially allowing an attacker with low privileges and local access to extract sensitive authentication data. The compromised credentials could then be used to access other computers or applications within the network, facilitating lateral movement or unauthorized access. The CVSS 3.1 base score is 5.5, reflecting a medium severity level, with an attack vector of local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and impacting confidentiality (C:H) but not integrity or availability. The vulnerability does not currently have known exploits in the wild, and no patches have been published at the time of this report. The risk primarily concerns environments where HTMO is deployed for email synchronization, especially in enterprises where credential confidentiality is critical. The lack of proper encryption or secure storage mechanisms for credentials in HTMO increases the risk of credential leakage if an attacker gains local access, which could be through compromised user accounts or insider threats. This vulnerability underscores the importance of secure credential management in client synchronization tools.
Potential Impact
For European organizations, the primary impact is the potential compromise of user credentials stored by HCL Traveler for Microsoft Outlook. This could lead to unauthorized access to email accounts and other connected systems, enabling lateral movement within corporate networks. Confidentiality breaches could expose sensitive corporate communications and data. Although the vulnerability requires local access and some privileges, insider threats or attackers who have already compromised a low-privilege account could escalate their access. This risk is particularly significant for sectors with high regulatory requirements around data privacy and security, such as finance, healthcare, and government. The absence of integrity or availability impact limits the scope of damage, but the confidentiality breach alone can have severe consequences including data leaks, compliance violations (e.g., GDPR), and reputational damage. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially once exploit code becomes available.
Mitigation Recommendations
Organizations should monitor HCL Software advisories closely and apply patches or updates as soon as they are released to address CVE-2024-42192. Until patches are available, restrict local access to systems running HTMO to trusted personnel only and enforce strict privilege management to minimize the risk of credential exposure. Implement endpoint security controls such as application whitelisting and behavior monitoring to detect suspicious local activity. Consider encrypting local storage volumes and using full disk encryption to protect stored credentials. Conduct regular audits of user privileges and access logs to identify potential misuse. Additionally, educate users about the risks of credential theft and enforce multi-factor authentication (MFA) on all critical systems to mitigate the impact of leaked credentials. Network segmentation can also limit lateral movement if credentials are compromised. Finally, review and harden configuration settings of HTMO and related infrastructure to minimize attack surface.
