GHSA-HHJV-JQ77-CMVX

zeptoclaw implements a blocklist to prevent dangerous commands running in android device shell, but this blocklist has several blocked commands with argements in the pattern literal, such as rm -f and rm -rf, this can be simply bypassed by using different orders for these arguments, such as rm -r -f or rm -fr etc.

Details

As in code src/tools/android/actions.rs#L413-L424, we can see the rm -f and rm -rf are hard coded and thus can be simply bypassed via rm -r -f or rm -fr etc.

pub async fn device_shell(adb: &AdbExecutor, cmd: &str) -> Result<String> {
    // Normalize whitespace for blocklist check
    let normalized: String = cmd.split_whitespace().collect::<Vec<_>>().join(" ");
    let lower = normalized.to_lowercase();

    let blocked = [
        "rm -rf",
        "rm -r",
        "reboot",
        "factory_reset",
        "wipe",
        "format",
        "dd if=",
        "mkfs",
        "flash",
        "fastboot",
    ];
    for pattern in &blocked {
        if lower.contains(pattern) {
            return Err(ZeptoError::Tool(format!(
                "Blocked dangerous command containing '{}'",
                pattern
            )));
        }
    }

PoC

Set up zeptoclaw with an Android tool and then run the command rm -f -r etc.

Unauthorized command executed in Android device.

Untrusted input reaches a shell command, allowing arbitrary commands to run on the host. Typical impact: code execution in the application's environment.

GHSA-HHJV-JQ77-CMVX has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.6.2); upgrading removes the vulnerable code path.

1. What is GHSA-HHJV-JQ77-CMVX? GHSA-HHJV-JQ77-CMVX is a high-severity OS command injection vulnerability in zeptoclaw (rust), affecting versions <= 0.6.1. It is fixed in 0.6.2. Untrusted input reaches a shell command, allowing arbitrary commands to run on the host.
2. How severe is GHSA-HHJV-JQ77-CMVX? GHSA-HHJV-JQ77-CMVX has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of zeptoclaw are affected by GHSA-HHJV-JQ77-CMVX? zeptoclaw (rust) versions <= 0.6.1 is affected.
4. Is there a fix for GHSA-HHJV-JQ77-CMVX? Yes. GHSA-HHJV-JQ77-CMVX is fixed in 0.6.2. Upgrade to this version or later.
5. Is GHSA-HHJV-JQ77-CMVX exploitable, and should I be worried? Whether GHSA-HHJV-JQ77-CMVX is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-HHJV-JQ77-CMVX is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-HHJV-JQ77-CMVX? Upgrade zeptoclaw to 0.6.2 or later.
