Computer vulnerabilities of Cisco Unified Communications Manager

security announce CVE-2017-3836

Cisco Unified Communications Manager: directory traversal

Synthesis of the vulnerability

An authenticated attacker can traverse directories of Cisco Unified Communications Manager, in order to read a file outside the service root path.
Severity: 2/4.
Creation date: 16/02/2017.
Revision date: 20/02/2017.

Description of the vulnerability

The Cisco Unified Communications Manager product offers a web service.

However, user's data are directly inserted in an access path. Sequences such as "/.." can thus be used to go in the upper directory.

An authenticated attacker can therefore traverse directories of Cisco Unified Communications Manager, in order to read a file outside the service root path.

vulnerability alert CVE-2017-3733

OpenSSL: denial of service via the "Encrypt-Then-Mac" option

Synthesis of the vulnerability

An attacker can change the state of the "Encrypt-Then-Mac" TLS option in a renegotiation with a server or client based on OpenSSL, in order to trigger a denial of service.
Severity: 2/4.
Creation date: 16/02/2017.
Identifiers: 2003480, 2003620, 2003673, 2004940, CERTFR-2017-AVI-035, cisco-sa-20170130-openssl, cpuapr2019, cpujan2018, cpuoct2017, CVE-2017-3733, HPESBGN03728, VIGILANCE-VUL-21871.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

OpenSSL implements the possibility of renegotiation of TLS option and parameters during a session.

However, for some combinations of algorithms, the negation of the state of the option "Encrypt-Then-Mac" generates a fatal error.

An attacker can therefore change the state of the "Encrypt-Then-Mac" TLS option in a renegotiation with a server or client based on OpenSSL, in order to trigger a denial of service.
