Vulnerability mechanics

Root cause

"The plugin trusts the X-Forwarded-For HTTP header to determine the client IP address without validation, enabling IP spoofing."

Attack vector

An attacker can spoof their IP address by injecting a crafted `X-Forwarded-For` header into the HTTP request [ref_id=1]. The plugin trusts this header without verification, allowing the attacker to impersonate any arbitrary IP address [CWE-290]. This could bypass IP-based access controls or logging mechanisms that the plugin relies on.

Affected code

The advisory does not specify exact files or functions. The plugin uses HTTP headers such as `X-Forwarded-For` to retrieve the client IP address [ref_id=1].

What the fix does

The advisory states the vulnerability is fixed in version 3.7 of the DoLogin Security plugin [ref_id=1]. No patch diff is provided, but the fix likely involves validating or discarding untrusted proxy headers and instead using a reliable source for the client IP, such as the direct socket connection.

Preconditions

  • networkThe attacker must be able to send HTTP requests to the WordPress site with arbitrary headers.
  • configThe DoLogin Security plugin must be installed and active with a version prior to 3.7.

Reproduction

The advisory does not include a detailed proof of concept, only noting that the plugin uses headers such as `X-Forwarded-For` to retrieve the IP address [ref_id=1]. No reproduction steps are documented in the bundle.
