## What is CVE-2020-7388?

CVE-2020-7388 is a critical authentication bypass vulnerability in Sage X3, published on 22 Jul 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Sage X3 Unauthenticated Remote Command Execution (RCE) as SYSTEM in AdxDSrv.exe component. By editing the client side authentication request, an attacker can bypass credential validation. While exploiting this does require knowledge of the installation path, that information can be learned by exploiting CVE-2020-7387. This issue was fixed in AdxAdmin 93.2.53, which ships with updates for on-premises versions of Sage X3 including Version 9 (components shipped with Syracuse 9.22.7.2 and later), Sage X3 HR & Payroll Version 9 (those components that ship with Syracuse 9.24.1.3), Version 11 (components shipped with Syracuse 11.25.2.6 and later), and Version 12 (components shipped with Syracuse 12.10.2.8 and later) of Sage X3. Other on-premises versions of Sage X3 are unsupported by the vendor.

Check this codebase for CVE-2020-7388 and fix it if it is affected.

What it is: CVE-2020-7388 is a critical authentication bypass vulnerability in Sage X3, published on 22 Jul 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-7388 exists.

Affected product: Sage X3. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
