Several vulnerabilities have been discovered in the OpenJDK Java runtime, resulting in denial of service, insecure TLS handshakes, bypass of sandbox restrictions or HTTP response splitting attacks.

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1507 advisory.

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization).
    Supported versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241.
    Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple     protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in     unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded.
    Note: Applies to client and server deployment of Java. This vulnerability can be exploited through     sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying     data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed     Java applets, such as through a web service. (CVE-2020-2756, CVE-2020-2757)

    (CVE-2020-2800)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported     versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other     than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly     impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE,     Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running     sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g.,     code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not     apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed     by an administrator). (CVE-2020-2803, CVE-2020-2805)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported     versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other     than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly     impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE,     Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running     sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g.,     code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not     apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed     by an administrator). (CVE-2020-2803, CVE-2020-2805)

Successful attacks of this vulnerability can result in     unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded.
    Note: Applies to client and server deployment of Java. This vulnerability can be exploited through     sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying     data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed     Java applets, such as through a web service.

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The version of AOS installed on the remote host is prior to 5.18. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.18 advisory.

  - When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to     Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP     connection. If such connections are available to an attacker, they can be exploited in ways that may be     surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped     with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected     (and recommended in the security guide) that this Connector would be disabled if not required. This     vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the     web application - processing any file in the web application as a JSP Further, if the web application     allowed file upload and stored those files within the web application (or the attacker was able to control     the content of the web application by some other means) then this, along with the ability to process a     file as a JSP, made remote code execution possible. It is important to note that mitigation is only     required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth     approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to     Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP     Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading     to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.
    (CVE-2020-1938)

  - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a     certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where,     the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by     the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
    (CVE-2019-19338)

  - The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which     allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.
    (CVE-2015-8035)
