## What is CVE-2019-9957?

CVE-2019-9957 is a medium-severity cross-site scripting vulnerability in n/a, published on 24 Jun 2019. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

Stored XSS within Quadbase EspressReport ES (ERES) v7.0 update 7 allows remote attackers to execute malicious JavaScript and inject arbitrary source code into the target pages. The XSS payload is stored by creating a new user account, and setting the username to an XSS payload. The stored payload can then be triggered by accessing the "Set Security Levels" or "View User/Group Relationships" page. If the attacker does not currently have permission to create a new user, another vulnerability such as CSRF must be exploited first.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

What it is: CVE-2019-9957 is a medium-severity cross-site scripting vulnerability in n/a, published on 24 Jun 2019. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2019-9957 in the wild and no public exploit code.

Affected product: n/a. 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.
