CVE-2020-10753 is a medium-severity vulnerability in Canonical Ubuntu Linux, published on 26 Jun 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. ### Official description A flaw was found in the Red Hat Ceph Storage RadosGW (Ceph Object Gateway). The vulnerability is related to the injection of HTTP headers via a CORS ExposeHeader tag. The newline character in the ExposeHeader tag in the CORS configuration file generates a header injection in the response when the CORS request is made. Ceph versions 3.x and 4.x are vulnerable to this issue. Weakness: CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), CWE-113 (Improper Neutralization of CRLF Sequences in HTTP Headers) ## Which versions are affected by CVE-2020-10753? 1 open source package ship an affected version, including ceph.

What it is: CVE-2020-10753 is a medium-severity vulnerability in Canonical Ubuntu Linux, published on 26 Jun 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. Exploitation: There is no known exploitation of CVE-2020-10753 in the wild and no public exploit code. Affected packages and fixed versions: - ceph (Bitnami): affected all versions; fixed in 14.2.21 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.
