New Nagios Software program Bugs Might Let Hackers Take Over IT Infrastructures

Nagios Software

As many as 11 safety vulnerabilities have been disclosed in Nagios community administration techniques, a few of which may very well be chained to realize pre-authenticated distant code execution with the very best privileges, in addition to result in credential theft and phishing assaults.

Industrial cybersecurity agency Claroty, which found the issues, stated flaws in instruments comparable to Nagios make them a horny goal owing to their “oversight of core servers, gadgets, and different vital parts within the enterprise community.” The problems have since been mounted in updates launched in August with Nagios XI 5.8.5 or above, Nagios XI Swap Wizard 2.5.7 or above, Nagios XI Docker Wizard 1.13 or above, and Nagios XI WatchGuard 1.4.8 or above.

SolarWinds and Kaseya had been seemingly focused not solely due to their giant and influential buyer bases, but additionally due to their respective applied sciences’ entry to enterprise networks, whether or not it was managing IT, operational know-how (OT), or web of issues (IoT) gadgets,” Claroty’s Noam Moshe stated in a write-up revealed Tuesday, noting how the intrusions focusing on the IT and community administration provide chains emerged as a conduit to compromise 1000’s of downstream victims.

Nagios Core is a well-liked open-source community well being software analogous to SolarWinds Community Efficiency Monitor (NPM) that is used for conserving tabs on IT infrastructure for efficiency points and sending alerts following the failure of mission-critical parts. Nagios XI, a proprietary web-based platform constructed atop Nagios Core, offers organizations with prolonged perception into their IT operations with scalable monitoring and a customizable high-level overview of hosts, providers, and community gadgets.

Chief among the many points are two distant code execution flaws (CVE-2021-37344, CVE-2021-37346) in Nagios XI Swap Wizard and Nagios XI WatchGuard Wizard, an SQL injection vulnerability (CVE-2021-37350) in Nagios XI, and a server-side request forgery (SSRF) affecting Nagios XI Docker Wizard, in addition to a post-authenticated RCE in Nagios XI’s Auto-Discovery software. The full listing of 11 flaws is as follows –

  • CVE-2021-37343 (CVSS rating: 8.8) – A path traversal vulnerability exists in Nagios XI under model 5.8.5 AutoDiscovery element and will result in post-authenticated RCE below the safety context of the person working Nagios.
  • CVE-2021-37344 (CVSS rating: 9.8) – Nagios XI Swap Wizard earlier than model 2.5.7 is weak to distant code execution by means of improper neutralization of particular parts utilized in an OS Command (OS Command injection).
  • CVE-2021-37345 (CVSS rating: 7.8) – Nagios XI earlier than model 5.8.5 is weak to native privilege escalation as a result of xi-sys.cfg is being imported from the var listing for some scripts with elevated permissions.
  • CVE-2021-37346 (CVSS rating: 9.8) – Nagios XI WatchGuard Wizard earlier than model 1.4.8 is weak to distant code execution by means of Improper neutralization of particular parts utilized in an OS Command (OS Command injection).
  • CVE-2021-37347 (CVSS rating: 7.8) – Nagios XI earlier than model 5.8.5 is weak to native privilege escalation as a result of getprofile.sh doesn’t validate the listing title it receives as an argument.
  • CVE-2021-37348 (CVSS rating: 7.5) – Nagios XI earlier than model 5.8.5 is weak to native file inclusion by means of an improper limitation of a pathname in index.php.
  • CVE-2021-37349 (CVSS rating: 7.8) – Nagios XI earlier than model 5.8.5 is weak to native privilege escalation as a result of cleaner.php doesn’t sanitize enter learn from the database.
  • CVE-2021-37350 (CVSS rating: 9.8) – Nagios XI earlier than model 5.8.5 is weak to SQL injection vulnerability in Bulk Modifications Instrument attributable to improper enter sanitization.
  • CVE-2021-37351 (CVSS rating: 5.3) – Nagios XI earlier than model 5.8.5 is weak to insecure permissions and permits unauthenticated customers to entry guarded pages by means of a crafted HTTP request to the server.
  • CVE-2021-37352 (CVSS rating: 6.1) – An open redirect vulnerability exists in Nagios XI earlier than model 5.8.5 that might result in spoofing. To use the vulnerability, an attacker might ship a hyperlink that has a specially-crafted URL and persuade the person to click on the hyperlink.
  • CVE-2021-37353 (CVSS rating: 9.8) – Nagios XI Docker Wizard earlier than model 1.1.3 is weak to SSRF attributable to improper sanitization in table_population.php
Prevent Ransomware Attacks

In a nutshell, the issues may very well be mixed by attackers to drop an online shell or execute PHP scripts and elevate their privileges to root, thus reaching arbitrary command execution within the context of the basis person. As a proof-of-concept, Claroty chained CVE-2021-37343 and CVE-2021-37347 to realize a write-what-where primitive, permitting an attacker to put in writing content material to any file within the system.

“[Network management systems] require in depth belief and entry to community parts as a way to correctly monitor community behaviors and efficiency for failures and poor effectivity,” Moshe stated.

“They could additionally prolong outdoors your community by means of the firewall to take care of distant servers and connections. Due to this fact, these centralized techniques could be a tasty goal for attackers who can leverage such a community hub, and try to compromise it as a way to entry, manipulate, and disrupt different techniques.”

The disclosure is the second time almost dozen vulnerabilities have been disclosed in Nagios. Earlier this Might, Skylight Cyber revealed 13 safety weaknesses within the community monitoring software that may very well be abused by an adversary to hijack the infrastructure with none operator intervention.
