Http only cookie bypass
CVE-2015-2156
Description
A vulnerability has been found in Play’s cookie handling code that could allow an attacker to bypass the httpOnly flag on sensitive cookies.
Impact
Any Play apps that reflect cookie values back into the body of a response are vulnerable to this. One example of when this might be a case is if using Play’s CSRF support with csrf.cookie.name configured, such that Play stores the csrf token in a cookie rather than the default of storing it in the session.
Affected Versions
Play 2.0 – 2.3.8
Workarounds
Upgrade to netty 3.9.8. For example:
libraryDependencies += “io.netty” % “netty” % “3.9.8.Final”
Fixes
The issue has been fixed in Play 2.3.9.
