CVE-2024-24808

Open redirect vulnerability due to incorrect validation of input values when redirecting users after login.

Details

pyload is validating URLs via the get_redirect_url function when redirecting users at login.

The URL entered in the next variable goes through the is_safe_url function, where a lack of validation can redirect the user to an arbitrary domain.

The documentation in the urllib library shows that improper URLs are recognized as relative paths when using the urlparse function. (https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlparse)

For example, When an unusual URL like https:///example.com is entered, urlparse interprets it as a relative path, but in the actual request it is converted to https://example.com due to url normalization.

PoC

1. In the next variable, insert the URL to which you want to redirect the user.
   

2. Check that it is possible to bypass url validation and redirect users to an arbitrary url.
   
   

An attacker can use this vulnerability to redirect users to malicious websites, which can be used for phishing and similar attacks.

Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.

CVE-2024-24808 has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.5.0b3.dev79); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2024-24808? CVE-2024-24808 is a medium-severity open redirect vulnerability in pyload-ng (pip), affecting versions < 0.5.0b3.dev79. It is fixed in 0.5.0b3.dev79. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.
2. How severe is CVE-2024-24808? CVE-2024-24808 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of pyload-ng are affected by CVE-2024-24808? pyload-ng (pip) versions < 0.5.0b3.dev79 is affected.
4. Is there a fix for CVE-2024-24808? Yes. CVE-2024-24808 is fixed in 0.5.0b3.dev79. Upgrade to this version or later.
5. Is CVE-2024-24808 exploitable, and should I be worried? Whether CVE-2024-24808 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-24808 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-24808? Upgrade pyload-ng to 0.5.0b3.dev79 or later.
