## What is CVE-2024-28077?

CVE-2024-28077 is a high-severity denial of service vulnerability in n/a, published on 26 Aug 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A denial-of-service issue was discovered on certain GL-iNet devices. Some websites can detect devices exposed to the external network through DDNS, and consequently obtain the IP addresses and ports of devices that are exposed. By using special usernames and special characters (such as half parentheses or square brackets), one can call the login interface and cause the session-management program to crash, resulting in customers being unable to log into their devices. This affects MT6000 4.5.6, XE3000 4.4.5, X3000 4.4.6, MT3000 4.5.0, MT2500 4.5.0, AXT1800 4.5.0, AX1800 4.5.0, A1300 4.5.0, S200 4.1.4-0300, X750 4.3.7, SFT1200 4.3.7, MT1300 4.3.10, AR750 4.3.10, AR750S 4.3.10, AR300M 4.3.10, AR300M16 4.3.10, B1300 4.3.10, MT300N-V2 4.3.10, and XE300 4.3.16.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-28077 and fix it if it is affected.

What it is: CVE-2024-28077 is a high-severity denial of service vulnerability in n/a, published on 26 Aug 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-28077 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.
