CVE Descriptions

The utf8_decode function in PHP before 5.3.4 does not properly handle non-shortest form UTF-8 encoding and ill-formed subsequences in UTF-8 data, which makes it easier for remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a crafted string.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Exploit information

EDB Verified : Yes

source: https://www.securityfocus.com/bid/44605/info PHP is prone to a vulnerability because it fails to sufficiently sanitize user-supplied input. Exploiting this issue can allow attackers to provide unexpected input and possibly bypass input-validation protection mechanisms. This can aid in further attacks that may utilize crafted user-supplied input. Versions prior to PHP 5.3.4 are vulnerable. <?php $ill=chr(0xf0).chr(0xc0).chr(0xc0).chr(0xa7); $ill=addslashes($ill); echo utf8_decode("$ill"); echo htmlspecialchars ($ill,ENT_QUOTES,"utf-8" ); ?>
