Language:

Synopsis

The remote Windows host has an application that may be affected by multiple vulnerabilities.

Description

The WinSCP program installed on the remote host is version 4.3.8, 4.3.9, 4.4.0 or 5.x prior to 5.5.4. It therefore contains a bundled version of OpenSSL prior to 1.0.1h which is affected by the following vulnerabilities :

- An error exists in the 'ssl3_read_bytes' function that permits data to be injected into other sessions or allows denial of service attacks. Note that this issue is exploitable only if SSL_MODE_RELEASE_BUFFERS is enabled. (CVE-2010-5298)

- A buffer overflow error exists related to invalid DTLS fragment handling that permits the execution of arbitrary code or allows denial of service attacks.
Note that this issue only affects OpenSSL when used as a DTLS client or server. (CVE-2014-0195)

- An error exists in the 'do_ssl3_write' function that permits a NULL pointer to be dereferenced, which could allow denial of service attacks. Note that this issue is exploitable only if SSL_MODE_RELEASE_BUFFERS is enabled. (CVE-2014-0198)

- An error exists related to DTLS handshake handling that could allow denial of service attacks. Note that this issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An error exists in the processing of ChangeCipherSpec messages that allows the usage of weak keying material.
This permits simplified man-in-the-middle attacks to be done. (CVE-2014-0224)

- An error exists in the 'dtls1_get_message_fragment' function related to anonymous ECDH cipher suites. This could allow denial of service attacks. Note that this issue only affects OpenSSL TLS clients. (CVE-2014-3470)

Solution

Upgrade to WinSCP version 5.5.4 or later.
