A newly discovered Linux vulnerability, dubbed 'Copy Fail,' enables attackers to gain root access on most open-source Linux distributions since 2017 using a minimal Python script. The flaw, added to CISA's KEV catalog, requires prior code execution but poses significant risks to cryptocurrency exchanges and blockchain services.
Malicious actors with code execution capability may gain root access on Linux systems using as few as 10 lines of Python, according to a researcher.
A newly discovered vulnerability could affect most open-source major Linux distributions released since 2017, according to security researchers. The flaw, titled “Copy Fail,” caught the attention of the US Cybersecurity and Infrastructure Agency , who added it to the Known Exploited Vulnerabilities catalog on Saturday,“10 lines of Python” may be all it takes: Researcher The vulnerability can allow attackers to gain root access across a wide range of Linux systems using a 732-byte Python script, though it requires prior code execution on the system to escalate privileges.that it only requires “10 lines of Python” to access root permissions on any affected system.
Linux is a widely used operating system by cryptocurrency exchanges, blockchain nodes and custodial services, due to its security and efficiency, meaning the vulnerability could potentially pose risks to the sector if attackers gain initial access.in an X post on Saturday that the flaw “is a trivially exploitable logic bug in Linux, reachable on all major distros released in the last 9 years. ”Cybersecurity firm Theori CEO Brian Pakin an X post on Saturday that he reported the vulnerability “privately” to the Linux kernel security team on March 23.
“We worked with them on patches, which landed in mainline on April 1. CVE assigned April 22. We disclosed publicly on April 29 with a full write-up and PoC,” Pak said. Cointelegraph is committed to independent, transparent journalism. This news article is produced in accordance with Cointelegraph’s
