Adobe Dreamweaver version 19.0 and earlier contains a critical insecure protocol implementation vulnerability that stems from improper handling of server message block smb protocol requests within its file transfer functionality. This weakness creates a pathway for attackers to exploit relay attacks against the application's network communications, potentially allowing unauthorized access to sensitive data through manipulated smb protocol interactions. The vulnerability exists in the application's protocol stack implementation where it fails to properly validate or authenticate incoming smb requests, creating an attack surface that can be leveraged by malicious actors.
The technical flaw manifests when Dreamweaver processes smb network requests during file operations, particularly when connecting to network shares or remote servers. The application's implementation lacks proper protocol validation mechanisms that would normally detect and prevent malicious relay attacks. According to CWE-310, this vulnerability represents a weakness in cryptographic key handling and protocol implementation, specifically in the area of secure communication protocols. The insecure implementation allows an attacker positioned within the network to intercept and manipulate smb protocol exchanges, potentially capturing authentication credentials or gaining access to restricted network resources.
Operationally, this vulnerability poses significant risks to organizations using Adobe Dreamweaver in enterprise environments where network shares and remote file systems are commonly accessed. Attackers can exploit this weakness by positioning themselves between the Dreamweaver application and target smb servers to perform relay attacks, potentially capturing authentication tokens or credentials used for network access. The impact extends beyond simple data disclosure as successful exploitation could enable attackers to escalate privileges within the network infrastructure, particularly in environments where Dreamweaver is used to manage web content across multiple servers. This vulnerability aligns with ATT&CK technique T1071.004 for application layer protocol usage and T1567.002 for credential harvesting through relay attacks.
Mitigation strategies should prioritize immediate patching of Adobe Dreamweaver to versions 20.0 or later where this vulnerability has been addressed. Organizations should also implement network segmentation to isolate Dreamweaver usage from critical network resources and employ network monitoring solutions to detect anomalous smb protocol behavior. Additional protective measures include disabling unnecessary smb functionality within Dreamweaver, implementing strict firewall rules for smb ports, and conducting regular security assessments of network protocols. The vulnerability demonstrates the importance of secure protocol implementation practices as outlined in OWASP Top Ten and NIST cybersecurity frameworks, particularly in applications that handle sensitive data and network communications. Regular vulnerability assessments and security updates remain critical for maintaining protection against similar insecure implementation flaws in enterprise applications.
