How to Fix CVE-2013-7379

To remediate this vulnerability, upgrade all affected Tomato dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

tomato fixed: 0.0.6 
npm install tomato@0.0.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls tomato

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2013-7379, inspect your project dependencies using npm:

npm ls tomato

Analyze the terminal output to locate any version of Tomato in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.6), your application is affected.

Note: The npm ls tomato command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Tomato, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of `tomato` prior to 0.0.6 are affected by a somewhat complex authentication bypass vulnerability in the admin service when only a single access key is configured on the server. The vulnerability allows an attacker to guess the password for the admin service, no matter how complex that password is, in less than 200 requests. ## Details The tomato API has an admin service that is enabled by setting up an `access_key` in the config options. This `access_key` is intended to protect the API admin from unauthorized access. Tomato verifies the `access_key` by checking to see if the server `access_key` incorporates the user provided value at any location. This allows an attacker to provide a single character as an `access_key`, and so long as the server key contains at least one instance of that character it will be considered a valid key. ## Proof of Concept This is the snippet of code that does the comparison to authorize requests. ``` if (access_key && config.master.api.access_key.indexOf(access_key) !== -1) { ``` For an access_key that is set to anything that includes the letter 'a' the following request would be authorized. ``` $ curl -X POST "http://localhost:8081/api/exec" -H "Content-Type: application/json" -d @test -H "access-key: a" { "cmd": "ls", "path": ".", "stdout": "app.js\nconfig.js\nlog\nnode_modules\nserver.js\n", "stderr": "" } ``` ## Recommendation Update to version 0.0.6 or later.
