[All PT0-001 Questions]

A security analyst was provided with a detailed penetration report, which was performed against the organization's DMZ environment. It was noted on the report that a finding has a CVSS base score of 10.0. Which of the following levels of difficulty would be required to exploit this vulnerability?

  • A. Very difficult; perimeter systems are usually behind a firewall.
  • B. Somewhat difficult; would require significant processing power to exploit.
  • C. Trivial; little effort is required to exploit this finding.
  • D. Impossible; external hosts are hardened to protect against attacks.

Tricky one. The question below is taken from PenTest+ Practice Tests Book - SYBEX A detailed penetration report was given to a security analyst. The penetration was conducted against the target organization’s DMZ environment. The report had a finding that the Common Vulnerability Scoring System (CVSS) had a base score of 1.0. To exploit this vulnerability, which level of difficulty would be required? A. Very difficult, because the perimeter systems are usually behind a firewall B. Somewhat difficult, because it would require powerful processing to exploit C. Trivial, because little effort would be required to exploit the findings D. Impossible, because the external hosts are hardened to protect against attacks The CVSS score from every material found from this question on the Internet is 10.0 but from the book is 1.0. Here is their explanation: C. - The Common Vulnerability Scoring System (CVSS) is an industry standard for assessing the severity of security vulnerabilities. It provides a technique for scoring each vulnerability on a variety of measures. Security analysts often use CVSS ratings to prioritize response actions. Each measure is given a descriptive rating and a numeric score. It must be just a typo but just a small detail I detected from this question.

IDK if there’s a typo or not, but since a CVSS score of 10.0 designates it as an incredibly critical vulnerability, it only stands to reason that it would be trivial to exploit. A score of 1.0 would be next to impossible to exploit. C is the correct answer in this case but I’d watch for this question on the exam.

i think C, I did alot of my own research and came to the conclusion that C. - The Common Vulnerability Scoring System (CVSS) is an industry standard for assessing the severity of security vulnerabilities. It provides a technique for scoring each vulnerability on a variety of measures. Security analysts often use CVSS ratings to prioritize response actions. Each measure is given a descriptive rating and a numeric score.

C. A good way to think of this is that in order to achieve a score of 10 its has to have all the CVSS flags set to the highest severity. The easy it is for the attacker the higher the severity rating will be.

How can a CVSS of 10 be trivial?

Trivial to exploit they are saying...but how do we know that? See my link above and a c/p from my WGU class ...I believe if you read into how the scoring is done, you can infer that it would be trivial...at least fro one whom knows what they are doing!!

Its a typo in this question. It should be a 1.0 If it was truly a 10.0 it would obvs not be trivial

A CVSS base score of 10.0 would mean that this vulnerability is given the most critical rating a vulnerability could achieve. which means basically their is an open door from the internet to a companies most restricted data on a server. an attacker could basically just connect and voila has everything he/she ever wanted. The answer is C because it would be trivial for the attacker to execute a successful attack on the target.

They're saying that the expolit is trivial (super easy) to action, therefore the issue is significant, low barrier to entry means every skiddy can do it.

The score for the base group is between 0 and 10, where 0 is the least severe and 10 is assigned to highly critical vulnerabilities. For example, a highly critical vulnerability could allow an attacker to remotely compromise a system and get full control. In addition, the score comes in the form of a vector string that identifies each of the components used to make up the score. The vector is used to record or transfer CVSS metric information in a concise form. The vector string starts with the label CVSS: and a numeric representation of the CVSS version, followed, for each metric, by a metric name in abbreviated form, a colon, :, and the associated metric value in abbreviated form. The following is an example of a CVSS 3.0 vector: CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L

Attack Vector (AV) represents the context in which a vulnerability can be exploited. It can assume four values:Network (N)Adjacent (A)Local (L)Physical (P) Attack Complexity (AC) represents the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability.Low (L)High (H) Privileges Required (PR) represents the level of privileges an attacker must have to exploit the vulnerability.None (N)Low (L)High (H) User Interaction (UI) captures whether a user interaction is needed to perform an attack.None (N)Required (R) Scope (S) captures the impact on systems other than the system being attacked:Unchanged (U)Changed (C) The Impact metrics include the following: Confidentiality (C) measures the degree of impact to the confidentiality of the systemLow (L)Medium (M)High (H) Integrity (I) measures the degree of impact to the integrity of the system. Low (L)Medium (M)High (H) Availability (A) measures the degree of impact to the availability of the system.assume the following values:Low (L)Medium (M)High (H)
