Vulnerability
Rankiteo Explanation
Attack without any consequences: Attack in which data is not compromised
Description: A high-severity vulnerability has been discovered in Realtek’s Bluetooth HCI Adaptor that allows local attackers to delete arbitrary files and potentially escalate privileges on affected systems. The vulnerability, tracked as CVE-2024-11857, was published to the GitHub Advisory Database and represents a significant security risk for systems utilizing Realtek Bluetooth hardware components. The flaw stems from a Link Following weakness classified under CWE-59 in the Common Weakness Enumeration database. This flaw enables local attackers with regular user privileges to exploit the Bluetooth HCI Adaptor’s file handling mechanisms through symbolic link manipulation. The attack vector requires minimal complexity and no user interaction, making it particularly concerning for security professionals.

Latest Global CVEs (Not Company-Specific)
Description
SummaryA command injection vulnerability (CWE-78) has been found to exist in the `wrangler pages deploy` command. The issue occurs because the `--commit-hash` parameter is passed directly to a shell command without proper validation or sanitization, allowing an attacker with control of `--commit-hash` to execute arbitrary commands on the system running Wrangler. Root causeThe commitHash variable, derived from user input via the --commit-hash CLI argument, is interpolated directly into a shell command using template literals (e.g., execSync(`git show -s --format=%B ${commitHash}`)). Shell metacharacters are interpreted by the shell, enabling command execution. ImpactThis vulnerability is generally hard to exploit, as it requires --commit-hash to be attacker controlled. The vulnerability primarily affects CI/CD environments where `wrangler pages deploy` is used in automated pipelines and the --commit-hash parameter is populated from external, potentially untrusted sources. An attacker could exploit this to: * Run any shell command. * Exfiltrate environment variables. * Compromise the CI runner to install backdoors or modify build artifacts. Credits Disclosed responsibly by kny4hacker. Mitigation * Wrangler v4 users are requested to upgrade to Wrangler v4.59.1 or higher. * Wrangler v3 users are requested to upgrade to Wrangler v3.114.17 or higher. * Users on Wrangler v2 (EOL) should upgrade to a supported major version.
