Overview<\/strong><\/p>\n

In this blog post, we will be discussing an important issue that has emerged in the cybersecurity landscape. Specifically, we’ll be focusing on CVE-2025-7393, a critical vulnerability in Drupal Mail Login, affecting versions from 3.0.0 before 3.2.0 and from 4.0.0 before 4.2.0. This vulnerability presents a substantial threat to the security<\/a> of user data and system integrity, especially in environments where Drupal is prevalent. This vulnerability is significant due<\/a> to its high CVSS score and the potential for system compromise or data leakage, therefore it is critical for users and administrators to take action to mitigate the risks.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-7393
\nSeverity: Critical, CVSS Score 9.8
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Drupal Mail Login | 3.0.0 – 3.1.9
\nDrupal Mail Login | 4.0.0 – 4.1.9<\/p>\n

How the Exploit Works<\/strong><\/p>\n

At its root, CVE-2025-7393 is a vulnerability that stems from an improper restriction<\/a> of excessive authentication attempts in Drupal Mail Login. This allows attackers to conduct a brute force<\/a> attack by systematically attempting all possible passwords until the correct one is found. Since the system doesn’t lock out users after a certain number of failed login<\/a> attempts, an attacker can continue guessing passwords indefinitely. This can lead to unauthorized<\/a> access, data leakage, or even a complete system compromise.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of a brute force attack exploiting<\/a> this vulnerability:<\/p>\n

POST \/user\/login HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nusername=admin&password=guess1\nPOST \/user\/login HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nusername=admin&password=guess2\n...<\/code><\/pre>\n
This example illustrates multiple login attempts by an attacker, systematically changing the password<\/a> parameter until the correct one is found.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
In response to this vulnerability, the vendor has issued a patch. Users are strongly advised to update their Drupal Mail Login to the latest version (3.2.0 for the 3.x branch and 4.2.0 for the 4.x branch). In cases where immediate patching is not possible, deploying a web<\/a> application firewall (WAF) or intrusion detection system (IDS) as a temporary mitigation measure can help protect against brute force attacks. However, these are only temporary solutions and updating the software is the most effective way to eliminate the vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
