VAR-201512-0071
Vulnerability from variot - Updated: 2025-04-12 23:14The MessageBrokerServlet servlet in Moxa OnCell Central Manager before 2.2 does not require authentication, which allows remote attackers to obtain administrative access via a command, as demonstrated by the addUserAndGroup action. Authentication is not required to exploit this vulnerability.The specific flaw exists within the MessageBrokerServlet servlet, which does not ensure a user is authenticated prior to accepting commands. An attacker can exploit this condition to perform various actions, including addUserAndGroup, to take full control of the product and achieve code execution on all managed hosts. There is a security vulnerability in the implementation. Moxa OnCell Central Manager is a set of private IP management software from Moxa. The software supports the configuration, management, and monitoring of remote devices, etc. over a private network over a network. An attacker could use this vulnerability to bypass the authentication mechanism and perform unauthorized operations. This may aid in further attacks. The vulnerability is caused by the fact that the program does not require authentication

ZDI declined an extension, but indicated we \"will wait a couple of days, for a status.\"09/18/2015 - ZDI notified ICS-CERT of the intent to 0-day the reports-- Mitigation:Given the nature of the vulnerability, the only salient mitigation strategy is to restrict interaction with the service to trusted machines. Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in and numerous other Microsoft Knowledge Base articles.-- Vendor Patch:See https://ics-cert.us-cert.gov/advisories/ICSA-15-328-01",

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
