A vulnerability classified as problematic has been found in October CMS up to 1.0.467 (Content Management System). Affected is an unknown part of the component Cookie Handler. The manipulation with an unknown input leads to a cookie validation vulnerability. CWE is classifying the issue as CWE-565. The product relies on the existence or values of cookies when performing security-critical operations, but it does not properly ensure that the setting is valid for the associated user. This is going to have an impact on integrity. CVE summarizes:

In OctoberCMS before version 1.0.468, encrypted cookie values were not tied to the name of the cookie the value belonged to. This meant that certain classes of attacks that took advantage of other theoretical vulnerabilities in user facing code (nothing exploitable in the core project itself) had a higher chance of succeeding. Specifically, if your usage exposed a way for users to provide unfiltered user input and have it returned to them as an encrypted cookie (ex. storing a user provided search query in a cookie) they could then use the generated cookie in place of other more tightly controlled cookies; or if your usage exposed the plaintext version of an encrypted cookie at any point to the user they could theoretically provide encrypted content from your application back to it as an encrypted cookie and force the framework to decrypt it for them. Issue has been fixed in build 468 (v1.0.468).

The weakness was released 07/31/2020 (GitHub Repository). The advisory is available at github.com. This vulnerability is traded as CVE-2020-15128 since 06/25/2020. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.

Upgrading to version 1.0.468 eliminates this vulnerability.
