--- type: Article title: Escalating SSRF in a Vulnerable Jira Instance to RCE via Docker Engine API description: A Jira SSRF is chained to an exposed, unauthenticated Docker Engine API. The server-side request reaches the local container daemon, creates an attacker-controlled container with host access, and turns a constrained web request primitive into remote command execution on the underlying system. resource: "https://www.andmp.com/2018/11/escalating-ssrf-in-vulnerable-jira.html" tags: [article, webseclist-reference, andmp-a-blog-about-infosec-bug-hunting-a, ssrf, docker, rce, attack-chain, owasp-a05-2021, owasp-a10-2021] generated: by: webseclist-refs/1 at: "2026-10-02T23:18:21+00:00" status: stable stale_after: 2027-10-02 sources: - id: original resource: "https://www.andmp.com/2018/11/escalating-ssrf-in-vulnerable-jira.html" title: Escalating SSRF in a Vulnerable Jira Instance to RCE via Docker Engine API author: "@username" also_at: [] authors: - "@username" canonical_url: "" cited_by: - "2018.md:104" commit: "" content_sha256: a401bc38cad3f04871f48d8f6b495278e46906b9e6c5b4f94220a2ac2ffd175a depth: full depth_reason: default kind: article language: "" licence: unknown original_url: "https://www.andmp.com/2018/11/escalating-ssrf-in-vulnerable-jira.html" published: "" publisher: Andmp | A blog about infosec, bug hunting and more! publisher_english: "" raw_sha256: f3d4e3c59295c4cfac50c2387982c90f7c1943c7f2812fde788fd18032520965 retrieved_from: "https://www.andmp.com/2018/11/escalating-ssrf-in-vulnerable-jira.html" retrieved_kind: live retrieved_utc: "2026-10-02T23:18:21+00:00" slug: andmp-a-blog-about-infosec-bug-hunting-and-more-escalating-ssrf-vulnerable-api snapshot: "" title_english: "" translation_file: "" translation_of: "" --- # Escalating SSRF in a Vulnerable Jira Instance to RCE via Docker Engine API **Escalating SSRF in a Vulnerable Jira Instance to RCE via Docker Engine API** - @username, Andmp | A blog about infosec, bug hunting and more!. - Published: date not stated - Original: - Preserved from: https://www.andmp.com/2018/11/escalating-ssrf-in-vulnerable-jira.html (live) on 2026-10-02 - Licence: unknown Rights remain with the original author and publisher.

This is just a repost of what I wrote there on /r/netsec, and formatting is a bit awkward. Due to some glitch I found out it couldn't be published there. Awhile back, I posted on [Twitter](https://twitter.com/payloadartist/status/1062248690679668736?s=20) about achieving Remote Code Execution in Jira instances deployed over Docker. It's a common sight these days, to come across internal bug trackers of large companies who simply don't firewall their internal network. As a result, one can achieve varying impacts, but *I believe, sky is the limit ;)* *Orangetsai* has previously demonstrated some *exceptional cases of acheiveing RCE via SSRF based vulnerabilities*, which further motivated me to research into this topic. Upon delving deeper, I found out that, *a huge number of Jira instances were exposed publically which itself is thought provoking and tempted me to look further into ways in which I could exploit it.* - I was able to earn a couple bug bounties along the way on *BugCrowd* by successfully demonstrating XSS, with cookies scoped to parent domains in those cases allowing me to execute a full fledged ATO attack via Reflected XSS using SSRF in the Vulnerable Jira instance. - The next considerable impact was *some critical information disclosure, which happened only at times, when you passed on a wrong or, malformed URL in your request* and Jira gave you an *interesting stack trace containing more internal information*. - Only in two counts of cases could I *leverage this to penetrate into the intranet of the concerned company* (which was interesting alone) and find some internal vulnerable software. The impact kept on increasing at each step as I progressed further and this was no more a simple report which most security researchers are tempted to make viz. Reflected XSS, SSRF and Exposed Jira Panels. Hence, I got something more to put in my security report. - As I kept digging deeper, I came across a *Jira instance which was deployed over Docker*. Ask how? I put together a simple Python script that would keep hitting the *consumerUri* parameter with different payloads like [::1], localhost, and the likes, also with some deliberately filthy payloads just to exfiltrate some information. The endpoint is https://[Jira-server host.tld]/jira/plugins/servlet/oauth/users/icon-uri?consumerUri= So, while monkey testing, and fuzzing I finally constructed this payload - https://[Jira-server-host.tld]/jira/plugins/servlet/oauth/users/icon-uri?consumerUri=http://[::1]:2375/containers/json Bam! We got some sensitive *docker credentials* stored as environment variables through an unauthenticated request to the Docker Engine API via an *SSRF vulnerability in that Jira instance* and are now in a position to conclude *we performed an RCE in an internal network where practically no XSS would hold that great an impact!* This could be rare but a notable case. Do you have some ideas on how to exploit this further? Do post your ideas on this!
