Researchers at risk detection and response firm Trellix have resurrected a 15-year-old Python vulnerability, displaying that it’s extra critical than initially believed and that it may have an effect on tons of of 1000’s of purposes.

The vulnerability in query is CVE-2007-4559, initially described as a listing traversal vulnerability in Python’s ‘tarfile’ module that would permit an attacker to remotely overwrite arbitrary information by convincing customers to course of specifically crafted tar archives.

The flaw was by no means correctly patched and as an alternative customers had been warned to not open archive information from untrusted sources.

Researchers at Trellix have now proven that an attacker can exploit the vulnerability to jot down arbitrary information and from there obtain malicious code execution normally. They demonstrated this towards a number of in style purposes that use the weak Python module, even displaying how an attacker may use social engineering to execute arbitrary code on the focused system with administrator privileges.

The cybersecurity agency has launched an open supply software, named Creosote, that can be utilized to scan tasks for this tarfile vulnerability. With this software they scanned public GitHub repositories and found 300,000 information containing the tarfile module, roughly 61% of which had been weak to assaults exploiting CVE-2007-4559.

With the assistance of GitHub, they carried out a extra complete scan that recognized 2.87 million open supply information containing the tarfile module throughout practically 590,000 distinctive repositories. If 61% of them are weak, the whole variety of open supply tasks affected by CVE-2007-4559 is roughly 350,000. These embrace purposes made by organizations within the growth, AI/ML, internet, information science, IT administration, and different industries.

As well as, the researchers famous that the problematic module is current in lots of closed-source tasks as nicely.

“This vulnerability is extremely simple to use, requiring little to no information about sophisticated safety matters. On account of this reality and the prevalence of the vulnerability within the wild, Python’s tarfile module has turn out to be an enormous provide chain subject threatening infrastructure all over the world,” Trellix stated.
