PHP 7.3.x < 7.3.1 Multiple vulnerabilities
critical Web Application Scanning Plugin ID 98242
New! Plugin Severity Now Using CVSS v3
The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.
Synopsis
PHP 7.3.x < 7.3.1 Multiple vulnerabilitiesDescription
According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.40, 7.1.x prior to 7.1.26, 7.2.x prior to 7.2.14 or 7.3.x prior to 7.3.1. It is, therefore, affected by multiple vulnerabilities:- An integer underflow condition exists in _gdContributionsAlloc function in gd_interpolation.c. An unauthenticated, remote attacker can have unspecified impact via vectors related to decrementing the u variable. (CVE-2016-10166)
- A heap-based buffer overflow condition exists in gdImageColorMatch due to improper calculation of the allocated buffer size. An attacker can exploit this, via calling imagecolormatch function with crafted image data as parameters. (CVE-2019-6977)
- A heap-based buffer over-read exists in the xmlrpc_decode function due to improper validation of input data. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause a heap out-of-bounds read or read-after-free condition, which could result in a complete system compromise. (CVE-2019-9020)
- A heap-based buffer over-read exists in the PHAR reading functions in the PHAR extension, due to improper implementation of memory operations. An unauthenticated, remote attacker can exploit this, via persuading a user to parse a specially crafted file name on the targeted system, to disclose sensitive information. (CVE-2019-9021)
- An out-of-bounds read error exists in the dns_get_record function due to improper parsing of DNS responses. An unauthenticated, remote attacker can exploit this, via a specially crafted DNS reply, to disclose memory contents. (CVE-2019-9022)
- Multiple heap-based buffer over-read instances exist in mbstring regular expression functions due to improper implementation of memory operations. An unauthenticated, remote attacker can exploit this by sending a specially crafted regular expression that contains multibyte sequences, to cause a condition that could allow the attacker to completely compromise the target system. (CVE-2019-9023)
- An out-of-bounds read error exists in the xmlrpc_decode function due to improper implementation of memory operations. An unauthenticated, remote attacker can exploit this, via a hostile XMLRPC server to cause PHP to read from memory outside of allocated areas. (CVE-2019-9024)
- An out-of-bounds read and write error exists in the mb_split function due to improper implementation of memory operations. An unauthenticated, remote attacker can exploit this by causing PHP to execute the memcpy function with a negative argument, to cause buffer over-read and over-write conditions which could allow the attacker to completely compromise the system. (CVE-2019-9025)
Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
