An DLL search order hijacking vulnerability in Apex One (on-premise) could allow a local attacker to execute arbitrary code as SYSTEM on affected installations.
This vulnerability is only exploitable on the on-premise version of Apex One and a potential attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
An OPIC interface access vulnerability in Apex One (on-premise) could allow a local attacker to trigger SYSTEM-level processes or manipulate quarantined files on affected installations.
This vulnerability is only exploitable on the on-premise version of Apex One and a potential attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
A heap buffer overflow in a specific Apex One service allows an authenticated local user to cause a deterministic denial-of-service by crashing the security agent service.
Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
An uncontrolled search path element in Apex One (on-premise) could allow a local attacker to escalate privileges on affected installations.
This vulnerability is only exploitable on the on-premise version of Apex One and a potential attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
A COM hijacking vulnerability Apex One/SEP agent could allow a local attacker to escalate privileges on affected installations.

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.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
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.
