Simple PHP Blog (SPHPBlog) search.php q Parameter XSS
Remote / Network Access
Loss of Confidentiality,
Loss of Integrity
Simple PHP Blog contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate 'q' variables upon submission to the 'search.php' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.

sphpBlog sphpBlog 0.4 .0
sphpBlog is affected by a cross-site scripting vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.
An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.
This issue is reported to affect sphpBlog version 0.4.0; earlier versions may also be vulnerable.
No exploit is required.
