CVE-2026-27758 is a cross-site request forgery (CSRF) vulnerability identified in the firmware of the SODOLA SL902-SWTGW124AS device produced by Shenzhen Hongyavision Technology Co., Ltd. (Sodola Networks). The vulnerability exists in firmware versions up to 200.1.20 within the device's management interface. CSRF vulnerabilities allow attackers to induce authenticated users to unknowingly submit forged HTTP requests, which the device processes with the user's privileges. In this case, an attacker crafts malicious web content that, when visited by an authenticated administrator or user of the device's management interface, triggers unauthorized configuration or administrative commands. The vulnerability requires no prior authentication or privileges from the attacker and no user interaction beyond visiting a malicious webpage. The CVSS 4.0 vector (AV:N/AC:L/AT:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no privileges required, user interaction required, and limited impact on integrity. The vulnerability could allow unauthorized changes to device settings, potentially disrupting network operations or compromising device security. No patches or public exploits are currently known, and the vulnerability was published on February 27, 2026. This issue falls under CWE-352, a common web security weakness related to CSRF. The device is typically deployed in network environments requiring secure management interfaces, making this vulnerability a concern for network administrators and security teams.

The primary impact of CVE-2026-27758 is the potential for unauthorized administrative or configuration changes to the SODOLA SL902-SWTGW124AS device. Such changes could disrupt network operations, degrade device security, or create persistent backdoors for attackers. Since the vulnerability exploits the trust relationship between the authenticated user and the device, attackers can leverage social engineering or phishing campaigns to induce users to visit malicious sites, triggering the CSRF attack. This could lead to unauthorized modifications such as altering firewall rules, changing routing configurations, or disabling security features. The vulnerability does not directly compromise confidentiality or availability but can indirectly lead to service disruptions or data exposure through misconfiguration. Organizations relying on this device for critical network infrastructure may face operational risks and increased attack surface. The lack of authentication requirements for exploitation and the ease of triggering the vulnerability via web browsers increase the risk profile. However, the need for user interaction (visiting a malicious webpage) somewhat limits the scope of exploitation. No known exploits in the wild reduce immediate risk but do not eliminate it. Overall, the vulnerability poses a medium risk to organizations using affected devices, especially those with exposed management interfaces or users susceptible to phishing.

1. Restrict access to the management interface of the SODOLA SL902-SWTGW124AS device by implementing network segmentation and firewall rules to limit access only to trusted administrative hosts. 2. Disable remote management interfaces if not required or restrict them to VPN connections to reduce exposure to external attackers. 3. Educate users and administrators about phishing and social engineering risks to reduce the likelihood of visiting malicious websites that could trigger CSRF attacks. 4. Implement web application firewalls (WAFs) or intrusion prevention systems (IPS) that can detect and block suspicious CSRF attack patterns targeting the device's management interface. 5. Monitor device logs and network traffic for unusual configuration changes or access patterns that may indicate exploitation attempts. 6. Regularly check for firmware updates or patches from Shenzhen Hongyavision Technology Co., Ltd. and apply them promptly once available. 7. Consider deploying multi-factor authentication (MFA) on the management interface if supported, to add an additional layer of protection against unauthorized actions. 8. Employ anti-CSRF tokens or other CSRF protection mechanisms in the management interface if firmware updates or vendor patches become available addressing this vulnerability. 9. Conduct periodic security assessments and penetration tests focusing on network device management interfaces to identify and remediate similar vulnerabilities proactively.
