Multiple PHP vulnerabilities

Multiple vulnerabilities have been discovered in PHP that could result in arbitrary code execution.

Risk is high for government, large enterprises and small businesses.

The security advisory was released on Thursday by the Multi-State Information Sharing & Analysis Center (MS-ISAC) to address over 20 security bug fixes in Hypertext Preprocessor (PHP). 

An overview of the PHP advisory: 

“Multiple vulnerabilities have been discovered in PHP, the most severe of which could allow an attacker to execute arbitrary code. PHP is a programming language originally designed for use in web-based applications with HTML content. PHP supports a wide variety of platforms and is used by numerous web-based software applications. Successfully exploiting the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the affected application. Depending on the privileges associated with the application, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploitation could result in a denial-of-service condition.”

Affected versions include: 

  • PHP 7.2 prior to 7.2.10
  • PHP 7.1 prior to 7.1.22
  • PHP 7.0 prior to 7.0.32
  • PHP 5.6 prior to 5.6.38

As of Thursday, there were no reports of these vulnerabilities being exploited in the wild. 

Administrators are highly encouraged to upgrade to the latest version of PHP as soon as possible.
