Exploits

CVE	Impact	Description	Version Affected	Details
CVE-2017-9506	HIGH	The IconUriServlet of the Atlassian OAuth Plugin from version 1.3.0 before version 1.9.12 and from version 2.0.0 before version 2.0.4 allows remote attackers to access the content of internal network resources and/or perform an XSS attack via Server Side Request Forgery (SSRF).	Jira < 7.3.5	CVE-2017-9506
CVE-2019-8449	LOW	The /rest/api/latest/groupuserpicker resource in Jira before version 8.4.0 allows remote attackers to enumerate usernames via an information disclosure vulnerability.	2.1 - 8.3.4	CVE-2019-8449
CVE-2019-11581	CRITICAL	Atlassian JIRA Template injection vulnerability RCE	Jira < 7.6.14	CVE-2019-11581
CVE-2019-8451	HIGH	Pre-authentication server side request forgery (SSRF) vulnerability found in the /plugins/servlet/gadgets/makeRequest resource.	Jira == 7.6.0 && Jira.7.6.0 < 7.13.9, 8.4.0	CVE-2019-8451

Majority of the bugs stated above poses Server-Side Request Forgery (SSRF) vulnerability, where attacker can abuse a specific functionality on the server to read or update internal resources. The attacker can supply or a modify a URL which the code running on the server will read or submit data to, and by carefully selecting the URLs, the attacker may be able to read server configuration such as AWS metadata, connect to internal services like HTTP enabled databases or perform post requests towards internal services which are not intended to be exposed.

Currently, some of the common Amazon AWS credentials leak attacks are present with an additional Custom Payload Option for sending crafted payloads for any cloud platform (Amazon AWS, Google Cloud, etc.). For sending custom payloads, take help from PayloadsAllTheThings — SSRF URL for Cloud Instances. Feel free to implement more post exploitation modules for vendor specifc deployments. For looking under the hood, read wiki.

Demonstration

Tests

The tests are next to the package i.e. tests are not part of the package, only of the repository. The reason is simply to keep the package small.

Running the unit tests

$ python3 -m unittest --verbose # Python 3 and up
