CVE-2007-1890

31
FAUCET Score

CVE-2007-1890 describes an integer overflow vulnerability in the msg_receive function of PHP 4 (prior to 4.4.5) and PHP 5 (prior to 5.2.1), specifically affecting FreeBSD and potentially other platforms. This flaw allows unauthenticated attackers to execute arbitrary code by manipulating maxsize values, as demonstrated by 0xffffffff. With a CVSS score of 7.5, this vulnerability is considered highly severe due to its low attack complexity and potential for complete compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, a public exploit (EDB-29808) exists, demonstrating its exploitability. Despite this, there is no evidence of active exploitation, and it has received minimal community discussion or media coverage.
