PARTIAL Summary
Stack-based buffer overflow in the cmd_submitf function in cgi/cmd.c in Nagios Core, possibly 4.0.3rc1 and earlier, and Icinga before 1.8.6, 1.9 before 1.9.5, and 1.10 before 1.10.3 allows remote attackers to cause a denial of service (segmentation fault) via a long message to cmd.cgi.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

For Debian 7 last seen 2020-03-17 modified 2016-05-09 plugin id 90945 published 2016-05-09 reporter This script is Copyright (C) 2016-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/90945 title Debian DLA-461-1 : nagios3 security update NASL family Debian Local Security Checks NASL id DEBIAN_DLA-1615.NASL description Several issues were corrected in nagios3, a monitoring and management system for hosts, services and networks. CVE-2018-18245 Maximilian Boehner of usd AG found a cross-site scripting (XSS) vulnerability in Nagios Core. This vulnerability allows attackers to place malicious JavaScript code into the web frontend through manipulation of plugin output. In order to do this the attacker needs to be able to manipulate the output returned by nagios checks, e.g. by replacing a plugin on one of the monitored endpoints. Execution of the payload then requires that an authenticated user creates an alert summary report which contains the corresponding output. CVE-2016-9566 It was discovered that local users with access to an account in the nagios group are able to gain root privileges via a symlink attack on the debug log file. CVE-2014-1878 An issue was corrected that allowed remote attackers to cause a stack-based buffer overflow and subsequently a denial of service (segmentation fault) via a long message to cmd.cgi. CVE-2013-7205 | CVE-2013-7108 A flaw was corrected in Nagios that could be exploited to cause a denial of service. This vulnerability is induced due to an off-by-one error within the process_cgivars() function, which can be exploited to cause an out-of-bounds read by sending a specially crafted key value to the Nagios web UI.

The update prevented log files from being displayed in the web interface. This update fixes the problem. We apologize for the inconvenience. It was discovered that Nagios incorrectly handled certain long strings. A remote authenticated attacker could use this issue to cause Nagios to crash, resulting in a denial of service, or possibly obtain sensitive information.
