2) Cryptographic issues

EUVDB-ID: #VU32619

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-4508

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

lighttpd before 1.4.34, when SNI is enabled, configures weak SSL ciphers, which makes it easier for remote attackers to hijack sessions by inserting packets into the client-server data stream or obtain sensitive information by sniffing the network. Per: http://download.lighttpd.net/lighttpd/security/lighttpd_sa_2013_01.txt "All versions from 1.4.24 (first version supporting SNI) up to and including 1.4.33."

Mitigation

Install update from vendor's website.

3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU32620

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-4559

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

lighttpd before 1.4.33 does not check the return value of the (1) setuid, (2) setgid, or (3) setgroups functions, which might cause lighttpd to run as root if it is restarted and allows remote attackers to gain privileges, as demonstrated by multiple calls to the clone function that cause setuid to fail when the user process limit is reached.

Mitigation

Install update from vendor's website.

4) Use-after-free

EUVDB-ID: #VU32621

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-4560

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing unspecified vectors that trigger FAMMonitorDirectory failures. A remote attackers can cause a denial of service (segmentation fault and crash).

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

Mitigation

Install update from vendor's website.

5) SQL injection

EUVDB-ID: #VU32559

Risk: Medium

CVSSv3.1: 6.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:P/RL:O/RC:C]

CVE-ID: CVE-2014-2323

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the host name, related to request_check_hostname. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.

Mitigation

Install update from vendor's website.

CVE-ID: CVE-2014-2324

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

Exploit availability: Yes

Description

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

Multiple directory traversal vulnerabilities in (1) mod_evhost and (2) mod_simple_vhost in lighttpd before 1.4.35 allow remote attackers to read arbitrary files via a .. (dot dot) in the host name, related to request_check_hostname.

Mitigation

7) Information disclosure

EUVDB-ID: #VU5214

Risk: Medium

CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:F/RL:O/RC:C]

CVE-ID: CVE-2014-3566

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.

Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.

Note: The vulnerability is known as POODLE.

Mitigation

Install update from vendor's website.
