CVE-2007-1900
CVSS v2.0
5.0
Medium
| Vector | AV:N/AC:L/Au:N/C:N/I:P/A:N |
Name of the Vulnerable Software and Affected Versions:
PHP versions 5.2.0 through 5.2.1
Description:
A CRLF injection issue exists due to an incorrect regular expression used in the FILTER VALIDATE EMAIL filter. This allows attackers to inject arbitrary e-mail headers via an e-mail address containing a '
' character, potentially enabling them to send unsolicited e-mail from the host.
Recommendations:
For PHP versions 5.2.0 and 5.2.1, consider disabling the FILTER VALIDATE EMAIL function until a patch is available to prevent exploitation. Restrict the use of the ext/filter extension to minimize the risk of malicious mail header injection. Avoid using e-mail addresses with newline characters in the affected filter to prevent bypassing the regular expression.
