Two vulnerabilities were discovered in Prosody, a lightweight Jabber/XMPP server. The Common Vulnerabilities and Exposures project identifies the following issues :
CVE-2016-1231 Kim Alvefur discovered a flaw in Prosody’s HTTP file-serving module that allows it to serve requests outside of the configured public root directory. A remote attacker can exploit this flaw to access private files including sensitive data. The default configuration does not enable the mod_http_files module and thus is not vulnerable.
CVE-2016-1232 Thijs Alkemade discovered that Prosody’s generation of the secret token for server-to-server dialback authentication relied upon a weak random number generator that was not cryptographically secure. A remote attacker can take advantage of this flaw to guess at probable values of the secret key and impersonate the affected domain to other servers on the network.
