Since \"nice\" can be abused to\ninvoke arbitrary commands, this misconfiguration enables an attacker with\naccess to the apache account to execute arbitrary commands as the root\nuser, resulting in a Local Privilege Escalation.\n\n\n[-] Proof of Concept:\n\nhttps://karmainsecurity.com/pocs/tvox_root_rce.php\n\n\n[-] Solution:\n\nNo official solution is currently available.\n\n\n[-] Disclosure Timeline:\n\n[22/05/2026] - Vendor was contacted, no response\n[27/05/2026] - Vendor was notified about this vulnerability, no response\n[27/05/2026] - Vendor was notified about 60-day disclosure deadline policy,\nno response\n[26/06/2026] - Vendor was contacted again along with CSIRT Italy, no\nresponse from CSIRT\n[08/07/2026] - First vendor response, asking for vulnerability details\n[09/07/2026] - Vulnerability details safely provided to the vendor\n[20/07/2026] - Vendor was contacted again, asking for an update\n[21/07/2026] - Vendor replied a security patch will be released by the end\nof July\n[21/07/2026] - CVE identifier requested\n[21/07/2026] - CVE identifier assigned\n[27/07/2026] - Reached 60-day disclosure deadline, still no official\nsolution\n[03/08/2026] - Public disclosure\n\n\n[-] CVE Reference:\n\nCVE-2026-64829 has been assigned to this vulnerability.\n\n\n[-] Credits:\n\nVulnerability discovered by Egidio Romano.\n\n\n[-] Original Advisory:\n\nhttps://karmainsecurity.com/KIS-2026-16\n_______________________________________________\nSent through the Full Disclosure mailing list\nhttps://nmap.org/mailman/listinfo/fulldisclosure\nWeb Archives & RSS: https://seclists.org/fulldisclosure/"
