CVE-1999-1271 is a vulnerability found in the initial versions of Macromedia Dreamweaver, a web development tool widely used in the late 1990s and early 2000s. The vulnerability arises from the use of weak encryption algorithms to store FTP passwords locally on the user's machine. FTP passwords saved by Dreamweaver are encrypted using a method that is easily reversible by local users with access to the same system. This means that any local user on the affected machine could potentially decrypt and retrieve the FTP credentials of other users, leading to unauthorized access to remote FTP servers. The vulnerability does not require network access or remote exploitation; it is strictly a local privilege issue. The CVSS score of 2.1 (low severity) reflects the limited scope and impact, as exploitation requires local access and does not affect confidentiality beyond password disclosure. There is no patch available for this vulnerability, and no known exploits have been reported in the wild. Given the age of the software and the vulnerability, modern versions of Dreamweaver or alternative tools are unlikely to be affected. However, legacy systems or archival environments that still use these early versions could be at risk. The vulnerability impacts confidentiality but does not affect integrity or availability of systems. No user interaction is required beyond local access, and the attack complexity is low once local access is obtained.

For European organizations, the direct impact of this vulnerability today is minimal due to the obsolescence of the affected Dreamweaver versions. However, organizations that maintain legacy systems or archives containing these early versions could face risks if multiple users share the same system. The primary impact is the potential compromise of FTP credentials, which could lead to unauthorized access to web servers or file repositories, potentially exposing sensitive data or allowing unauthorized content modifications. This could be particularly concerning for organizations with legacy web infrastructure still managed via FTP. The vulnerability does not enable remote exploitation, so the risk is confined to environments where local user accounts are shared or insufficiently isolated. In environments with strong user separation and endpoint security, the risk is further reduced. Nonetheless, the exposure of FTP credentials could facilitate lateral movement or privilege escalation if attackers gain local access through other means.

To mitigate this vulnerability, European organizations should: 1) Avoid using the initial versions of Macromedia Dreamweaver that contain this weak encryption flaw. Upgrade to newer versions or alternative modern web development tools that employ secure credential storage mechanisms. 2) Enforce strict user account separation and limit local user privileges to prevent unauthorized access to other users' files. 3) Implement endpoint security controls such as disk encryption and access control lists to protect stored credentials. 4) Where legacy systems must be maintained, consider removing stored FTP passwords from Dreamweaver and use secure credential management solutions instead. 5) Transition away from FTP to more secure file transfer protocols like SFTP or FTPS, which provide encrypted authentication and data transfer. 6) Regularly audit systems for legacy software and credentials stored in weakly protected formats. 7) Educate users about the risks of storing passwords in legacy applications and encourage use of password managers with strong encryption.
