CVE-2023-41715: CWE-269 Improper Privilege Management in SonicWall SonicOS
SonicOS post-authentication Improper Privilege Management vulnerability in the SonicOS SSL VPN Tunnel allows users to elevate their privileges inside the tunnel.
AI Analysis
Technical Summary
CVE-2023-41715 is a high-severity vulnerability identified in SonicWall's SonicOS SSL VPN Tunnel, specifically categorized under CWE-269: Improper Privilege Management. This vulnerability allows an authenticated user within the SSL VPN tunnel to escalate their privileges beyond what is normally permitted. The affected versions include multiple releases of SonicOS, notably versions 7.0.1-5119 and earlier, 7.0.1-5129 and earlier, 6.5.4.4-44v-21-2079 and earlier, and 6.5.4.12-101n and earlier. The CVSS v3.1 base score is 8.8, indicating a high impact with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This means the vulnerability can be exploited remotely over the network without user interaction, requires low privileges (authenticated user), and results in high confidentiality, integrity, and availability impacts. The core issue lies in improper privilege management post-authentication, allowing users who have already gained access to the SSL VPN tunnel to elevate their privileges, potentially gaining administrative or otherwise unauthorized access within the network environment. This could enable attackers to manipulate sensitive data, disrupt services, or further penetrate the network. No known exploits are currently reported in the wild, but the vulnerability's nature and high CVSS score suggest it is a critical risk if left unpatched. SonicWall has not yet published official patches or mitigation links at the time of this report.
Potential Impact
For European organizations, this vulnerability poses a significant risk due to the widespread use of SonicWall VPN appliances in enterprise and government sectors for secure remote access. Exploitation could lead to unauthorized access to internal networks, data breaches involving sensitive personal and corporate information, and disruption of critical services. Given the high confidentiality, integrity, and availability impacts, organizations could face regulatory penalties under GDPR if personal data is compromised. Additionally, the ability to escalate privileges within the VPN tunnel could facilitate lateral movement by attackers, increasing the risk of ransomware deployment or espionage activities. The post-authentication nature means that attackers need initial access, which could be obtained through compromised credentials or phishing, making the vulnerability a potent vector in multi-stage attacks. The lack of known exploits currently provides a window for proactive mitigation, but the potential impact on business continuity and data protection is severe.
Mitigation Recommendations
European organizations should immediately audit their SonicWall SonicOS VPN deployments to identify affected versions. Until official patches are released, organizations should implement strict access controls and monitor VPN user activities for anomalous behavior indicative of privilege escalation attempts. Enforce multi-factor authentication (MFA) to reduce the risk of credential compromise. Network segmentation should be applied to limit the scope of access granted through the VPN tunnel. Additionally, organizations should review and tighten user privilege assignments within the VPN environment, ensuring the principle of least privilege is strictly enforced. Regularly update and patch SonicOS as soon as vendor updates become available. Employ intrusion detection and prevention systems (IDPS) to detect unusual privilege escalation patterns. Finally, conduct user awareness training to mitigate risks of credential theft that could lead to exploitation of this vulnerability.
