computer vulnerability alert 18266

Joomla com_cckseblod: directory traversal

Synthesis of the vulnerability

An attacker can traverse directories of Joomla com_cckseblod, in order to read a file outside the service root path.
Impacted products: Joomla Extensions ~ not comprehensive.
Severity: 2/4.
Consequences: data reading.
Provenance: internet client.
Creation date: 09/11/2015.
Identifiers: VIGILANCE-VUL-18266.

Description of the vulnerability

The com_cckseblod extension can be installed on Joomla.

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 attacker can therefore traverse directories of Joomla com_cckseblod, in order to read a file outside the service root path.

computer vulnerability CVE-2015-5309

PuTTY: integer overflow of ECH

Synthesis of the vulnerability

An attacker, who owns a malicious SSH server, can invite the victim to connect with Putty, to generate an integer overflow with ECH, in order to trigger a denial of service, and possibly to run code.
Impacted products: Debian, Fedora, openSUSE, openSUSE Leap, PuTTY, X2GoClient.
Severity: 2/4.
Consequences: user access/rights, denial of service on client.
Provenance: intranet server.
Creation date: 09/11/2015.
Identifiers: CERTFR-2015-AVI-540, CVE-2015-5309, DSA-3409-1, FEDORA-2015-3d17682c15, FEDORA-2015-5ad4a1f151, openSUSE-SU-2015:2023-1, VIGILANCE-VUL-18265.

Description of the vulnerability

The PuTTY product emulates a Unix terminal.

This terminal supports ANSI escape sequences. The ECH (erase characters, "ESC [ n X") sequence deletes several characters. However, if the number of characters is too large, an integer overflows, and Putty alters data located outside the current buffer.

An attacker, who owns a malicious SSH server, can therefore invite the victim to connect with Putty, to generate an integer overflow with ECH, in order to trigger a denial of service, and possibly to run code.
