Web Server Vulnerabilities Updates

Drupal Remote Code Execution Vulnerability CVE-2018-7602

• A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple attack vectors on a Drupal site, which could result in the site being compromised. This vulnerability is related to Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-002. Both SA-CORE-2018-002 and this vulnerability is being exploited in the wild.

If you are running 7.x, upgrade to Drupal 7.59.

If you are running 8.5.x, upgrade to Drupal 8.5.3.

If you are running 8.4.x, upgrade to Drupal 8.4.8.

Drupal Cross Site Scripting Vulnerability Drupal Security Release

• In Drupal 8 before 8.5.2 and 8.4.7 a cross site scripting vulnerability exists. CKEditor, a third-party JavaScript library included in Drupal core, has fixed a cross-site scripting (XSS) vulnerability. The vulnerability stemmed from the fact that it was possible to execute XSS inside CKEditor when using the image2 plugin (which Drupal 8 core also uses).

WordPress Login Redirect Vulnerability CVE-2018-10100

• Before WordPress 4.9.5, the redirection URL for the login page was not validated or sanitized if forced to use HTTPS.

WordPress Hostname Vulnerability CVE-2018-10101

• Before WordPress 4.9.5, the URL validator assumed URLs with the hostname localhost were on the same host as the WordPress server.

WordPress Cross-Site Scripting Vulnerability CVE-2018-10102

• Before WordPress 4.9.5, the version string was not escaped in the get_the_generator function, and could lead to XSS in a generator tag.

PHP Out of Bounds Denial of Service Vulnerability CVE-2018-10549

• An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. exif_read_data in ext/exif/exif.c has an out-of-bounds read for crafted JPEG data because exif_iif_add_value mishandles the case of a MakerNote that lacks a final '\0' character.

PHP Denial of Service Vulnerability CVE-2018-10548

• An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. ext/ldap/ldap.c allows remote LDAP servers to cause a denial of service (NULL pointer dereference and application crash) because of mishandling of the ldap_get_dn return value.

PHP Cross-Site Scripting Vulnerability CVE-2018-10547

• An issue was discovered in ext/phar/phar_object.c in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. There is Reflected XSS on the PHAR 403 and 404 error pages via request data of a request for a .phar file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-5712.

PHP Denial of Service Vulnerability CVE-2018-10546

• An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. An infinite loop exists in ext/iconv/iconv.c because the iconv stream filter does not reject invalid multibyte sequences.

PHP Denial of Service Vulnerability CVE-2018-10545

• An issue was discovered in PHP before 5.6.35, 7.0.x before 7.0.29, 7.1.x before 7.1.16, and 7.2.x before 7.2.4. Dumpable FPM child processes allow bypassing opcache access controls because fpm_unix.c makes a PR_SET_DUMPABLE prctl call, allowing one user (in a multiuser environment) to obtain sensitive information from the process memory of a second user's PHP applications by running gcore on the PID of the PHP-FPM worker process.

Oracle WebLogic Server Remote Code Execution Vulnerability CVE-2018-2628

• Vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware (subcomponent: WLS Core Components). Supported versions that are affected are 10.3.6.0, 12.1.3.0, 12.2.1.2 and 12.2.1.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via T3 to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle WebLogic Server.

CVSS 3.0 Base Score 9.8 (Confidentiality, Integrity and Availability impacts).

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
