Description

This security bulletin contains information about 2 vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2010-3870)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4:


The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via a crafted string. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


2) Format string error (CVE-ID: CVE-2010-2950)

CWE-ID: CWE-134 - Use of Externally-Controlled Format String

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Format string vulnerability in stream.c in the phar extension in PHP 5.3.x through 5.3.3 allows context-dependent attackers to obtain sensitive information (memory contents) and possibly execute arbitrary code via a crafted phar:// URI that is not properly handled by the phar_stream_flush function, leading to errors in the php_stream_wrapper_log_error function. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-2094.
