The answer is that public exploit code being available online is a key indicator of an exploitable vulnerability from scan findings. This is because the existence of a working proof-of-concept or Metasploit module dramatically reduces the skill and time required to weaponize the flaw, moving it from a theoretical risk to a practical attack vector. On the CompTIA PenTest+ PT0-002 exam, this concept tests your ability to prioritize findings beyond raw CVSS scores, as scanners often flag critical severity based on factors like remote attack vector and low complexity, but the true exploitability hinges on whether a public tool exists. A common trap is assuming a high CVSS score alone guarantees exploitability, when in reality a critical vulnerability without public code may require custom development. Remember the mnemonic “PATCH” for exploitability indicators: Public exploit, Active exploitation, Technical impact, Conflicting patches, High attack vector.
PT0-002 Practice Question: Information Gathering and Vulnerability Scanning
This PT0-002 practice question tests your understanding of information gathering and vulnerability scanning. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A penetration tester is analyzing the results of a vulnerability scan. Which of the following findings indicate that a vulnerability is likely exploitable? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The vulnerability is classified as 'critical' by the scanner
Option A is correct because a 'critical' classification by the scanner typically indicates a high-severity vulnerability with a CVSS base score of 9.0 or higher, which often corresponds to remotely exploitable flaws that can lead to complete compromise. Scanners like Nessus or OpenVAS assign critical severity based on factors such as attack vector, complexity, and impact, making such vulnerabilities highly likely to be exploitable in practice.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The vulnerability is classified as 'critical' by the scanner
Why this is correct
Critical severity often indicates that exploitation is likely and impact is high.

✗
CVSS base score of 4.0
Why it's wrong here
A score of 4.0 is medium severity; it does not necessarily mean it is easy to exploit.
✗
The vulnerability has been patched by the vendor
Why it's wrong here
If patched, the vulnerability may not be exploitable if the patch is applied.
✓
Public exploit code is available online
Why this is correct
Availability of exploit code increases the likelihood of successful exploitation.

✗
Multiple hosts share the same vulnerability
Why it's wrong here
Widespread vulnerability does not imply exploitability; it may still be difficult to exploit.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between vulnerability severity and exploitability, where candidates mistakenly assume a medium CVSS score (e.g., 4.0) or widespread presence (multiple hosts) implies the vulnerability is easily exploitable, ignoring that exploitability requires a working exploit or low attack complexity.
Detailed technical explanation
How to think about this question
The CVSS scoring system uses metrics like Attack Vector (AV), Attack Complexity (AC), Privileges Required (PR), and User Interaction (UI) to calculate a base score; a score of 4.0 might require local access or high complexity, making exploitation unlikely in a typical penetration test. Public exploit code availability (Option D) directly indicates that a working proof-of-concept or weaponized exploit exists, which is a strong signal for exploitability—tools like Metasploit or Exploit-DB often host such code, and a tester can use it to validate the vulnerability. In real-world engagements, a 'critical' scanner finding often triggers immediate manual verification, as it may involve remote code execution without authentication, such as EternalBlue (MS17-010) or Log4Shell (CVE-2021-44228).

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
