PHP Denial of Service Vulnerability

CVE-2018-19395

 

ext/standard/var.c in PHP 5.x through 7.1.24 on Windows allows attackers to cause a denial of service (NULL pointer dereference and application crash) because com and com_safearray_proxy return NULL in com_properties_get in ext/com_dotnet/com_handlers.c, as demonstrated by a serialize call on COM("WScript.Shell").

 

IBM WebSphere Directory Traversal Vulnerability

CVE-2018-1797

 

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 using Enterprise bundle Archives (EBA) could allow a local attacker to traverse directories on the system. By persuading a victim to extract a specially-crafted ZIP archive containing "dot dot slash" sequences (../), an attacker could exploit this vulnerability to write to arbitrary files on the system. Note: This vulnerability is known as "Zip-Slip". IBM X-Force ID: 149427.

 

IBM WebSphere Cross Site Scripting Vulnerability

CVE-2018-1643

 

The Installation Verification Tool of IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 144588.

 

IBM WebSphere Cross Site Scripting Vulnerability

CVE-2018-1798

 

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 149428.

 

IBM WebSphere Privilege Escalation Vulnerability

CVE-2018-1840

 

IBM WebSphere Application Server 8.5 and 9.0 could allow a remote attacker to gain elevated privileges on the system, caused when a security domain is configured to use a federated repository other than global federated repository and then migrated to a newer release of WebSphere Application Server. IBM X-Force ID: 150813.

 

IBM WebSphere XML External Entity Injection Vulnerability

CVE-2018-1905

 

IBM WebSphere Application Server 9.0.0.0 through 9.0.0.9 is vulnerable to a XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources. IBM X-Force ID: 152534.

 

Nginx Sensitive Information Disclosure Vulnerability

CVE-2016-16845

 

nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process rash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker can trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.

 

Nginx Denial of Service Vulnerability

CVE-2016-16844

 

nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive CPU usage. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file.

 

Nginx Denial of Service Vulnerability

CVE-2016-16843

 

nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file.
