2) Privilege escalation

EUVDB-ID: #VU264

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-0714

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a local attacker to bypass security manager restriction.

A local attacker, who controls web application, can abuse functionality of StandardManager and PersistentManager to gain control over sessions persistence, stored in files, in database or in custom Sore. Since session persistence is performed by Tomcat code with the permissions assigned to Tomcat internal code, the attacker can place specially crafted object into a session and execute arbitrary code on vulnerable system with elevated privileges.

Successful exploitation of the vulnerability may allow a local attacker to gain elevated privileges on the system.

CVE-ID: CVE-2015-5346

CWE-ID: CWE-384 - Session Fixation

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise accounts of other users.

The vulnerability exists due to an insecure way of handling sessions. A remote attacker can leverage the requestedSessionSSL field for an unintended request, related to CoyoteAdapter.java and Request.java and hijack web sessions of web application users.

4) Security Manager bypass

EUVDB-ID: #VU263

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-0706

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

The vulnerability allows a local attacker to obtain potentially sensitive information.

A local attacker, who controls web application, can use StatusManagerServlet, when a security manager was configured, to obtain potentially sensitive information, which belongs to other users. The attacker will be able to obtain a list of all deployed applications and a list of the HTTP request lines for all requests currently being processed. This could have exposed sensitive information from other web applications, such as session IDs, to the web application.

Successful exploitation of the vulnerability may allow a local attacker to gain access to potentially sensitive information.

Mitigation

Install updates from vendor's repository.

5) Directory disclosure

EUVDB-ID: #VU262

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2015-5345

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information.

When accessing a directory protected by a security constraint with a URL that did not end in a slash, Tomcat would redirect to the URL with the trailing slash thereby confirming the presence of the directory before processing the security constraint. It was therefore possible for a user to determine if a directory existed or not, even if the user was not permitted to view the directory.

Successful exploitation of the vulnerability may allow a remote attacker to confirm existence of directories on the system.

Mitigation

Install updates from vendor's repository.

6) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU87534

Risk: Medium

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2016-0763

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

Exploit availability: No

Description

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to missing authorization within the setGlobalContext() method in org/apache/naming/factory/ResourceLinkFactory.java. A remote user can bypass intended SecurityManager restrictions and read or write to arbitrary application data, or cause a denial of service (application disruption), via a web application that sets a crafted global context.

Mitigation

Install updates from vendor's repository.

7) Resource exhaustion

EUVDB-ID: #VU197

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2016-3092

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause denial of service conditions on the target system.

The vulnerability exists due to input validation error when processing very long boundary strings within the MultipartStream class in Apache Commons Fileupload. A remote user can cause denial of service conditions by sending specially crafted boundary string and consume excessive CPU resources.

Successful exploitation of this vulnerability may result in denial of service attack.

Mitigation

Install updates from vendor's repository.
