Description

This security bulletin contains information about 2 vulnerabilities.


1) Path traversal (CVE-ID: CVE-2016-1231)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in the HTTP file-serving module (mod_http_files) in Prosody 0.9.x before 0.9.9. A remote authenticated attacker can send a specially crafted HTTP request and remote attackers to read arbitrary files via a . (dot dot) in an unspecified path.


2) Input validation error (CVE-ID: CVE-2016-1232)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The mod_dialback module in Prosody before 0.9.9 does not properly generate random values for the secret token for server-to-server dialback authentication, which makes it easier for attackers to spoof servers via a brute force attack. <a href="https://cwe.mitre.org/data/definitions/338.html">CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)</a>
