APSB13-10: Whats considered the maximum safe max post params
we applied apsb13-10 update cf9 , have run issues applications. setting defaulted 100, compared tomcat's 10,000 max post param default, wondering reason behind 100 default , considered max safe value setting. there no specific details in cves or apsb-13-10 bulletin seem indicate for. details in adobe bulletin versus cves seem contradict each other murkying vulnerabilities are being patched.
the descrepency refering in adobe bulletin state "this hotfix resolves information leak can occur in multi-threaded use cases. issue not exploitable remotely (cve-2013-1387)." when looking @ particular cve says "unspecified vulnerability in adobe coldfusion 9.0 before update 10, 9.0.1 before update 9, 9.0.2 before update 4, , 10 before update 9 allows attackers impersonate users via unknown vectors." not remotely exploitable information leakage differeing impersonating users.
are 2 remotely exploitable issues being fixed noted cves, or 1 cve information leak? max post param setting have either of these issues being patched, , considered safe maximum post param setting?
the postparameterlimit introduced in apsb12-06, when installed apsb13-10 got apsb12-06 , several other prior hotfixes.
