@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data
A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE
COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM
This is a list of recent vulnerabilities for which exploits are
available. System administrators can use this list to help in
prioritization of their remediation activities. The Qualys Vulnerability
Research Team compiles this information based on various exploit
frameworks, exploit databases, exploit kits and monitoring of internet
activity.
ID: CVE-2019-7226
Title: ABB PB610 Multiple Security Vulnerabilities
Vendor: ABB
Description: ABB PB610 Panel Builder 600 is exposed to an authentication bypass vulnerability. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. The ABB IDAL HTTP server CGI interface contains a URL that allows an unauthenticated attacker to bypass authentication and gain access to privileged functions. Specifically, /cgi/loginDefaultUser creates a session in an authenticated state and returns the session ID along with what may be the username and cleartext password of the user. An attacker can then supply an IDALToken value in a cookie, which will allow them to perform privileged operations such as restarting the service with /cgi/restart. A GET request to /cgi/loginDefaultUser may result in "1 #S_OK IDALToken=532c8632b86694f0232a68a0897a145c admin admin" or a similar response.
CVSS v2 Base Score: 5.8 (AV:A/AC:L/Au:N/C:P/I:P/A:P)
ID: CVE-2019-12817
Title: Linux kernel Local Privilege Escalation Vulnerability
Vendor: Linux
Description: Linux Kernel is exposed to a local privilege escalation vulnerability. A local attacker can exploit this issue to gain elevated privileges. arch/powerpc/mm/mmu_context_book3s64.c in the Linux kernel for powerpc has a bug where unrelated processes may be able to read/write to one another's virtual memory under certain conditions via an mmap above 512 TB.
CVSS v2 Base Score: 6.9 (AV:L/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2019-12974
Title: ImageMagick Multiple Security Vulnerabilities
Vendor: ImageMagick
Description: A NULL pointer dereference in the function ReadPANGOImage in coders/pango.c and the function ReadVIDImage in coders/vid.c in ImageMagick allows remote attackers to cause a denial of service via a crafted image. Successfully exploiting these issues may allow an attacker to gain access to sensitive information, bypass certain security restrictions and to perform unauthorized actions or cause a denial of service condition. This may aid in launching further attacks.
CVSS v2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:N/I:N/A:P)
ID: CVE-2019-12972
Title: GNU Binutils Heap Based Buffer Overflow Vulnerability
Vendor: GNU
Description: GNU Binutils is exposed to a heap based buffer overflow vulnerability. An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), where a heap based buffer over read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing ' ' character. Attackers can exploit this issue to cause a denial of service condition, denying service to legitimate users.
CVSS v2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:N/I:N/A:P)
ID: CVE-2019-3961
Title: Nessus Cross Site Scripting Vulnerability
Vendor: Nessus
Description: Nessus is exposed to a cross site scripting vulnerability because it fails to properly sanitize user supplied input. An unauthenticated, remote attacker could potentially exploit this vulnerability via a specially crafted request to execute arbitrary script code in a users browser session. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie based authentication credentials and launch other attacks.
CVSS v2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:N/I:P/A:N)
ID: CVE-2019-12939
Title: LiveZilla Server SQL Injection Vulnerability
Vendor: LiveZilla
Description: LiveZilla Server is exposed to an SQL injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query. An attacker may leverage this issue to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
ID: CVE-2019-11707
Title: Mozilla Firefox and Firefox ESR Denial of Service Vulnerability
Vendor: Mozilla
Description: Mozilla Firefox and Firefox ESR are exposed to a denial of service vulnerability. Attackers can exploit these issues to crash the application, denying service to legitimate users. A type confusion vulnerability can occur when manipulating JavaScript objects due to issues in Array.pop. This can allow for an exploitable crash.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
