Vulnerability from variot - Updated: 2024-11-23 21:51

Triangle MicroWorks SCADA Data Gateway 3.02.0697 through 4.0.122, 2.41.0213 through 4.0.122 allows remote attackers cause a denial-of-service condition due to a lack of proper validation of the length of user-supplied data, prior to copying it to a fixed-length stack-based buffer. Authentication is not required to exploit this vulnerability. Triangle MicroWorks Library for control systems provided by the company DNP3 Outstation Libraries , And data management applications for control systems SCADA Data Gateway The following vulnerabilities exist in. DNP3 Outstation Libraries * Stack-based buffer overflow (CWE-121) - CVE-2020-6966 SCADA Data Gateway * Wrong type (CWE-843) - CVE-2020-10611 * Out-of-bounds read (CWE-125) - CVE-2020-10613 * Stack-based buffer overflow (CWE-121) - CVE-2020-10615The expected impact depends on each vulnerability, but it may be affected as follows. * Code execution stopped by an unauthenticated remote third party - CVE-2020-6966 * Arbitrary code executed by an unauthenticated remote third party - CVE-2020-10611 * Sensitive information stolen by an unauthenticated remote third party - CVE-2020-10613 * Interfering with service operations by an unauthenticated remote third party (DoS) Be attacked - CVE-2020-10615. An attacker can leverage this vulnerablity to execute code in the context of SYSTEM. Triangle MicroWorks SCADA Data Gateway is a SCADA data gateway product of American Triangle MicroWorks company. The vulnerability stems from the program's failure to correctly verify the length of data provided by users. A remote attacker can use the specially crafted input to exploit the vulnerability and cause a denial of service

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

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.

    Related by attack behaviour

    Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
