Reproduction

  1. Set the environment variables for jira and openai
import os
from langchain.utilities.jira import JiraAPIWrapper
os.environ["JIRA_API_TOKEN"] = "your jira api token"
os.environ["JIRA_USERNAME"] = "your username"
os.environ["JIRA_INSTANCE_URL"] = "your url"
os.environ["OPENAI_API_KEY"] = "your openai key"
  1. Run jira
jira = JiraAPIWrapper()
output = jira.run('other',"exec(\"import os;print(os.popen('id').read())\")")
  1. The id command will be executed.
    Commands can be change to others and attackers can execute arbitrary code.

Expected behavior

The code can be executed without any check.

I think the options here are to either a) check code to a limited number of allowed actions, or b) remove the "other" method from the tool.

It looks like we want the jira tool to:

  1. Create an issue
  2. search jira
  3. get projects

I'm not sure what other functionality we want to extend to with self.other, maybe y'all know how to proceed best

This is another critical bug that is deployment breaking for many: https://nvd.nist.gov/vuln/detail/CVE-2023-34540

Replace JIRA Arbitrary Code Execution vulnerability with finer grain …
a2f191a 
…API wrapper (#6992)

This fixes #4833 and the critical vulnerability
https://nvd.nist.gov/vuln/detail/CVE-2023-34540

Previously, the JIRA API Wrapper had a mode that simply pipelined user
input into an `exec()` function.
[The intended use of the 'other' mode is to cover any of Atlassian's API
that don't have an existing
interface](https://github.com/hwchase17/langchain/blob/cc33bde74ff2e050a400e4451e04ff5b32c4a7bd/langchain/tools/jira/prompt.py#L24)

Fortunately all of the [Atlassian JIRA API methods are subfunctions of
their `Jira`
class](https://atlassian-python-api.readthedocs.io/jira.html), so this
implementation calls these subfunctions directly.

As well as passing a string representation of the function to call, the
implementation flexibly allows for optionally passing args and/or
keyword-args. These are given as part of the dictionary input. Example:
```
    {
        "function": "update_issue_field",   #function to execute
        "args": [                           #list of ordered args similar to other examples in this JiraAPIWrapper
            "key",
            {"summary": "New summary"}
        ],
        "kwargs": {}                        #dict of key value keyword-args pairs
    }
```

the above is equivalent to `self.jira.update_issue_field("key",
{"summary": "New summary"})`

Alternate query schema designs are welcome to make querying easier
without passing and evaluating arbitrary python code. I considered
parsing (without evaluating) input python code and extracting the
function, args, and kwargs from there and then pipelining them into the
callable function via `*f(args, **kwargs)` - but this seemed more
direct.

Hi. I still getting this error in scan: https://nvd.nist.gov/vuln/detail/CVE-2023-34540
Can we reopen?

@aiakubovich for Jira, this should be fixed in most recent version, so updating langchain version should remove the error

Confirming this is fixed in #6992 and published in v0.0.225. Versions v0.0.225 and newer should not be affected.

You can confirm this by noting:

@aiakubovich I'm opening a PR to the advisory database to update that CVE as fixed in v0.0.225, which should stop it from being reported on your end once your scanner tool sees the updated database entry.

If you're still seeing this problem ~next week, please give us a ping and we can dig in deeper together.

Thanks for your patience on this! We're working to make this process smoother in the future.
