CVE-2026-27752 in SODOLA SL902-SWTGW124AS
Summary
by MITRE • 02/27/2026
SODOLA SL902-SWTGW124AS firmware versions through 200.1.20 transmit authentication credentials over unencrypted HTTP, allowing attackers to capture credentials. An attacker positioned to observe network traffic between a user and the device can intercept credentials and reuse them to gain administrative access to the gateway.

The vulnerability identified as CVE-2026-27752 affects the SODOLA SL902-SWTGW124AS gateway device with firmware versions up to 200.1.20. This security flaw represents a critical weakness in the device's communication protocols that directly impacts the confidentiality and integrity of administrative access credentials. The device's failure to implement encrypted communication channels creates an exploitable condition that allows attackers to intercept sensitive information during transmission. The vulnerability specifically manifests in the device's use of unencrypted HTTP protocols for authentication processes, which violates fundamental security principles for network device communications. This flaw enables man-in-the-middle attacks and credential interception that can lead to complete administrative control of the affected gateway.
The technical implementation of this vulnerability stems from the device's reliance on plaintext HTTP communication for authentication exchanges. When users attempt to access the device's administrative interface, authentication credentials are transmitted without encryption, making them visible to any network observer. This design flaw places the device at significant risk within environments where network traffic interception is possible, such as public wifi networks, compromised internal networks, or when devices are accessed through unsecured connections. The lack of Transport Layer Security (TLS) or Secure Sockets Layer (SSL) encryption in the communication stack creates an attack surface that aligns with CWE-319, which specifically addresses the exposure of sensitive information through improper network communication. The vulnerability's impact is amplified by the fact that administrative credentials are often reused across multiple systems, potentially allowing attackers to escalate their access beyond the initial compromised device.
The operational impact of this vulnerability extends far beyond the immediate compromise of a single device. An attacker who successfully intercepts administrative credentials can gain complete control over the gateway's configuration, potentially allowing them to modify network settings, redirect traffic, implement malicious firewall rules, or establish persistent backdoors. This access can enable further lateral movement within the network, as gateways often serve as critical network infrastructure points that provide access to internal systems. The vulnerability's exploitation can lead to significant consequences including data breaches, network disruption, and potential compliance violations, particularly in regulated environments where network security is paramount. From an adversarial perspective, this vulnerability aligns with ATT&CK technique T1071.004 for Application Layer Protocol: DNS, as attackers can leverage the compromised gateway to establish covert communication channels and exfiltrate data.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The most critical immediate action involves updating the device firmware to a version that implements encrypted communication protocols, specifically requiring HTTPS for all administrative access. Organizations should implement network monitoring solutions to detect and alert on unusual authentication patterns or potential credential interception attempts. Network segmentation and firewall rules should be configured to limit direct administrative access to the device from untrusted networks. Additionally, implementing multi-factor authentication and role-based access controls can provide additional layers of protection even if credentials are compromised. The vulnerability serves as a reminder of the importance of secure communication protocols in network device design and highlights the necessity of following security best practices such as those outlined in NIST SP 800-53 for network security controls. Regular vulnerability assessments and security audits should be conducted to identify similar weaknesses in other network infrastructure components, as the prevalence of unencrypted communication in network devices remains a significant concern in enterprise security environments.
