CVE-2017-1000117

A malicious third-party can give a crafted "ssh://..." URL to an unsuspecting victim, and an attempt to visit the URL can result in any program that exists on the victim's machine being executed. Such a URL could be placed in the .gitmodules file of a malicious project, and an unsuspecting victim could be tricked into running "git clone --recurse-submodules" to trigger the vulnerability.

The summary, impact and action text on this page are written by our AI analysis pipeline, or taken from the NVD description when a CVE was imported from NVD. They are not the vendor's wording: check them against the sources. A longer AI executive summary and technical analysis are generated for signed-in accounts on the Max plan.

Fix and mitigation

WAF and other mitigations

Can a WAF block it? Partly. Open redirects pass an outside URL in a parameter. A WAF can block external URLs in known redirect parameters.

Also consider: allow-list redirect targets

Based on the weakness type only; no CVE-specific evidence yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Common questions

Is CVE-2017-1000117 being exploited?

Not confirmed. CVE-2017-1000117 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 78% probability of exploitation in the next 30 days.

How severe is CVE-2017-1000117?

CVE-2017-1000117 is rated High with a CVSS score of 8.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Is there a patch for CVE-2017-1000117?

Yes. A fix has been recorded for CVE-2017-1000117. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.

What does CVE-2017-1000117 affect?

CVE-2017-1000117 affects git-scm:git. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.

Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
