Sightings

Presentation

Users have the possibility to add observations to vulnerabilities with different types of sightings, such as: seen, exploited, not exploited, confirmed, not confirmed, patched, and not patched.

Type	Description	Negative/Opposite
seen	The vulnerability was mentioned, discussed, or observed by the user.	No
confirmed	The vulnerability has been validated from an analyst’s perspective	Yes
published-proof-of-concept	A public proof of concept is available for this vulnerability.	No
exploited	The vulnerability was observed as exploited by the user who reported the sighting.	Yes
patched	The vulnerability was observed as successfully patched by the user who reported the sighting.	Yes

You can find the corresponding definition of this MISP taxonomy here.

Example

Example of a sighting object:

{
    "uuid": "f6ed692b-2656-4ce0-bcf1-eaf12dfe281d",
    "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd",
    "author": "8dfa6142-8c6d-4072-953e-71c85404aefb",
    "type": "seen",
    "source": "https://infosec.exchange/users/cve/statuses/113389560858828548",
    "vulnerability": "CVE-2024-10312",
    "creation_timestamp": "2024-10-29T08:36:31.492184Z"
}

A source is not necessarily an URL. It can be any string, for example, the UUID of a MISP event.

Automation tools

Realistically, sightings are more likely to be created programmatically, for instance, based on observations gathered from social networks, network captures, etc.

Our tools on the Python Package Index (PyPI):

Tool	Description
ShadowSight	A client that retrieves vulnerability observations from the The Shadowserver Foundation and pushes them to a Vulnerability-Lookup instance.
FediVuln	A client to gather vulnerability-related information from the Fediverse.
BlueSkySight	A client to gather vulnerability-related information from Bluesky.
MISPSight	A client that retrieves vulnerability observations from a MISP server and pushes them to a Vulnerability-Lookup instance.
NucleiVuln	A client designed to retrieve vulnerability-related observations from the Nuclei Git repository of templates and pushes them to a Vulnerability-Lookup instance.
ExploitDBSighting	A client that retrieves vulnerability observations from Exploit-DB and pushes them to a Vulnerability-Lookup instance.
KEVSight	A client to generate sightings for Vulnerability-Lookup from the Known Exploited Vulnerabilities (KEV) catalog.
GistSight	A client for gathering vulnerability-related information from GitHub Gists.
MetasploitSight	A client designed to retrieve vulnerability-related information from the modules available in Metasploit.

If you want to create your own sighting tool, it’s recommended to use PyVulnerabilityLookup, a Python library to access Vulnerability-Lookup via its REST API.
