Multiple vulnerabilities in IBM SAN Volume Controller and Storwize Family

1) Directory disclosure

EUVDB-ID: #VU262

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-5345

CWE-ID: CWE-200 - Information exposure

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.

CVE-ID: CVE-2015-5351

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.

Mitigation

Install update from vendor's website.

4) Security Manager bypass

EUVDB-ID: #VU263

Risk: Low

CVSSv3.1: 3.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-0706

CWE-ID: CWE-200 - Information exposure

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 update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

5) Privilege escalation

EUVDB-ID: #VU264

Risk: Low

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

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.

Mitigation

Install update from vendor's website.

6) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU87534

Risk: Medium

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

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 update from vendor's website.

7) Limited directory traversal

EUVDB-ID: #VU261

Risk: Low

CVSSv3.1: 3.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-5174

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

Exploit availability: No

Description

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

The vulnerability exists due to incorrect validation of paths in getResource(), getResourceAsStream() and getResourcePaths() methods within ServletContext. A local attacker can bypass security manager restrictions using directory traversal sequences and view directory listing outside the $CATALINA_BASE/webapps folder.

Successful exploitation of the vulnerability may allow a local attacker to obtain names of files and folder on vulnerable system.

Mitigation

Install update from vendor's website.
