This signature detects attempts to exploit a known vulnerability in the Edge Side Includes (ESI) component of the Squid proxy. Successful exploitation allows the attacker to cause a denial of service condition for all clients accessing the Squid service.
client_side_request.cc in Squid 3.x before 3.5.18 and 4.x before 4.0.10 allows remote servers to cause a denial of service (crash) via crafted Edge Side Includes (ESI) responses.
