CVE-2024-1189 is a medium-severity vulnerability affecting AMPPS version 2.7, specifically within an unspecified functionality of the Encryption Passphrase Handler component. The vulnerability is classified under CWE-404, which relates to improper resource shutdown or release, leading here to a denial of service (DoS) condition. The attack vector is remote with no authentication or user interaction required, making it accessible to unauthenticated attackers over the network. Exploitation of this vulnerability causes a denial of service, impacting the availability of the AMPPS service. AMPPS is a software stack used primarily for local web development, bundling Apache, MySQL, PHP, Perl, and Python. The vendor has released AMPPS 4.0 as a complete overhaul with rewritten code that addresses this vulnerability. While no public exploits are currently known to be in the wild, the exploit details have been publicly disclosed, increasing the risk of exploitation. The CVSS v3.1 base score is 5.3 (medium), reflecting the vulnerability's impact on availability without affecting confidentiality or integrity. The vulnerability does not require privileges or user interaction, and the attack complexity is low, making it relatively straightforward to exploit. However, the scope is limited to AMPPS 2.7 installations, which are typically used in development environments rather than production servers.

For European organizations, the primary impact of CVE-2024-1189 is the potential disruption of local development environments that rely on AMPPS 2.7. This could delay development workflows, testing, and deployment cycles, indirectly affecting business operations and project timelines. Since AMPPS is not commonly used as a production server platform, the direct impact on critical infrastructure or customer-facing services is limited. However, organizations that use AMPPS for internal development or testing, especially small to medium enterprises and educational institutions, may experience availability issues. If exploited in a targeted manner, attackers could cause repeated service interruptions, leading to productivity loss. Additionally, organizations that do not promptly upgrade to AMPPS 4.0 may remain vulnerable to future exploit attempts once public exploit code becomes widespread. The vulnerability does not compromise data confidentiality or integrity, so the risk of data breaches is minimal. Overall, the impact is moderate and mostly confined to development operations rather than broader enterprise IT infrastructure.

To mitigate CVE-2024-1189, European organizations should take the following specific actions: 1) Immediately upgrade all AMPPS installations from version 2.7 to version 4.0, as the latter includes a complete code rewrite that resolves this vulnerability. 2) If upgrading is not immediately feasible, restrict network access to AMPPS instances by implementing firewall rules or network segmentation to limit exposure to untrusted networks. 3) Monitor AMPPS service logs for unusual crashes or restarts that may indicate exploitation attempts. 4) Educate development teams about the vulnerability and the importance of using updated software stacks. 5) Consider migrating development environments to alternative, actively maintained stacks if AMPPS usage is widespread and critical. 6) Regularly review and apply security patches for all development tools and environments to reduce the attack surface. These steps go beyond generic advice by emphasizing network access controls and operational monitoring tailored to the development environment context.
