17
FAUCET Score

CVE-2005-3389 describes a vulnerability in the parse_str function of PHP versions 4.x up to 4.4.0 and 5.x up to 5.0.5. An attacker can exploit this by providing a single parameter that triggers a memory_limit termination, causing PHP to inadvertently enable the register_globals directive. This allows for potential manipulation of PHP application variables that would otherwise be protected. The vulnerability has a CVSS score of 5.0 (Medium), indicating a network-based attack with low complexity and potential for partial integrity impact, but no confidentiality or availability impact. Its EPSS score is low, suggesting a low probability of exploitation. There is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage are minimal, indicating a low level of public attention.
