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

In the vast realm of project management software, Kanboard has carved a niche for itself with its focus on the Kanban methodology. However, a critical vulnerability was discovered in versions prior to 1.2.46, which exposes users to potential system compromise or data leakage. This vulnerability, identified as CVE-2025-52560, allows attackers to craft malicious password reset<\/a> links that can leak the reset token to an attacker-controlled domain. This post is aimed at cybersecurity professionals who need to understand this vulnerability<\/a>, its potential impact, and the mitigation measures that can be taken against it.<\/p>\n

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

CVE ID: CVE-2025-52560
\nSeverity: Critical (8.1 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: System compromise or data<\/a> leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Kanboard | Prior<\/a> to 1.2.46<\/p>\n

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

The vulnerability lies within the password<\/a> reset functionality of Kanboard. When the `application_url` configuration is unset (which is the default behavior), Kanboard allows password reset<\/a> emails to be sent with URLs derived from the unvalidated Host header. This loophole allows an attacker to craft a malicious password reset<\/a> link that leaks the token to an attacker-controlled domain. If a victim, possibly an administrator, clicks the poisoned link, their account can be hijacked.<\/p>\n

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

A conceptual example of how the vulnerability might be exploited is as follows:<\/p>\n

GET \/password_reset?token=[token]&email=[victim's email] HTTP\/1.1\nHost: attacker-controlled-domain.com<\/code><\/pre>\n
In this request, the attacker substitutes the `[token]` and `[victim’s email]` with the actual token and victim’s email. This request would be contained within the malicious password reset<\/a> link, and when a victim clicks it, the token would be sent to the attacker-controlled domain, allowing the attacker to reset the victim’s password.<\/p>\n
Mitigation<\/strong><\/p>\n
The most effective way to mitigate this vulnerability is to apply the vendor patch by upgrading Kanboard<\/a> to version 1.2.46 or later, where this issue has been patched. In the absence of an upgrade, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may serve as temporary mitigation. It is also recommended to set the `application_url` configuration to prevent the usage of the Host header in password reset<\/a> URLs.<\/p>\n","protected":false},"excerpt":{"rendered":"
