New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote web server is affected by multiple vulnerabilities.

Description

The version of IBM HTTP Server running on the remote host is affected by multiple vulnerabilities, including the following:

- IBM GSKit (IBM DB2 for Linux, UNIX and Windows 9.7, 10.1, 10.5, and 11.1) duplicates the PRNG state across fork() system calls when multiple ICC instances are loaded which could result in duplicate Session IDs and a risk of duplicate key material. (CVE-2018-1426)

- The GSKit (IBM Spectrum Protect 7.1 and 7.2) and (IBM Spectrum Protect Snapshot 4.1.3, 4.1.4, and 4.1.6) CMS KDB logic fails to salt the hash function resulting in weaker than expected protection of passwords. A weak password may be recovered. Note: After update the customer should change password to ensure the new password is stored more securely. Products should encourage customers to take this step as a high priority action. (CVE-2018-1447)

- There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very similar to CVE-2015-3193 but must be treated as a separate problem. (CVE-2017-3732)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to IBM HTTP Server version 7.0.0.45, 8.5.5.14, 9.0.0.8, or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PI91913 or PI94222.
