Question 624 of 1,152

Threats, Vulnerabilities, and Mitigations →hardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to change the default credentials on the internal admin console and restrict access to approved management hosts. This is the highest priority because default credentials represent an active, easily exploitable vulnerability that requires no additional exploit development—an attacker on the corporate VLAN can simply log in and gain full control of the server, bypassing the firewall entirely. On the Security+ SY0-701 exam, this tests your understanding of vulnerability prioritization, where the most immediately exploitable risk outweighs a patched or mitigated issue like the backported OpenSSL fix. A common trap is focusing on the critical CVE or the open port, but the key is that default credentials provide a direct, zero-effort attack vector. Remember the mnemonic: "Default is Defeat"—always remediate default credentials before chasing patched CVEs.

SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question

This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 vulnerability scan of a Linux application server reports these findings: OpenSSL 3.0.7 is flagged with a critical CVE, but the distribution vendor note says the fix was backported. Port 8443 is bound to all interfaces, yet a firewall blocks it from the internet. The internal admin console on that port still uses the default admin/admin credentials and is reachable from the corporate VLAN. Which issue should be remediated first?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

Question 1hardmultiple choice

Open the full VLAN trunking answer →

A
Upgrade OpenSSL immediately, because the reported CVE proves the package is exploitable as installed.
Why wrong: The vendor note indicates the fix was backported, so the version number alone may not represent true exposure. That makes this finding less urgent than an actively reachable default credential issue.
B
Ignore the 8443 service, because the internet firewall already prevents external exposure.
Why wrong: Internal reachability still matters. A service reachable from the corporate VLAN with default credentials is exploitable even if it is blocked from the internet.
C
Change the default credentials on the internal admin console and restrict access to only approved management hosts.
Default credentials on a reachable administrative interface are the highest-risk issue in the list. The console is accessible from the corporate VLAN, so an internal attacker or compromised endpoint could log in immediately without needing a vulnerability exploit. The OpenSSL finding may be a false positive due to backporting, and the firewall already limits internet reach, but default admin/admin credentials create direct compromise risk.
D
Leave the console as-is and focus only on changing the bind address to 127.0.0.1.
Why wrong: Binding locally would reduce exposure, but the question asks for the first remediation step. Active default credentials on a reachable admin interface are more immediately dangerous than interface binding alone.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Change the default credentials on the internal admin console and restrict access to only approved management hosts.

Option C is correct because the most immediate risk is that an attacker on the corporate VLAN can access the internal admin console using default credentials (admin/admin). This bypasses the firewall and allows full control of the application server. Even though OpenSSL has a backported fix, the default credentials represent an active, easily exploitable vulnerability that requires no additional exploit development.

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.

✗
Upgrade OpenSSL immediately, because the reported CVE proves the package is exploitable as installed.
Why it's wrong here
The vendor note indicates the fix was backported, so the version number alone may not represent true exposure. That makes this finding less urgent than an actively reachable default credential issue.
✗
Ignore the 8443 service, because the internet firewall already prevents external exposure.
Why it's wrong here
Internal reachability still matters. A service reachable from the corporate VLAN with default credentials is exploitable even if it is blocked from the internet.
✓
Change the default credentials on the internal admin console and restrict access to only approved management hosts.
Why this is correct
Default credentials on a reachable administrative interface are the highest-risk issue in the list. The console is accessible from the corporate VLAN, so an internal attacker or compromised endpoint could log in immediately without needing a vulnerability exploit. The OpenSSL finding may be a false positive due to backporting, and the firewall already limits internet reach, but default admin/admin credentials create direct compromise risk.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates focus on the critical CVE and the firewall rule, overlooking that default credentials on an internally reachable service pose a more immediate and easily exploitable risk than a patched vulnerability or a network control that does not protect against internal threats.

Detailed technical explanation

How to think about this question

Backporting is a common practice in enterprise Linux distributions where security patches are applied to older package versions without changing the version number, so a version string alone cannot confirm vulnerability status. Default credentials (e.g., admin/admin) are often hardcoded in web-based admin consoles and can be exploited via automated scripts or tools like Hydra within seconds. The corporate VLAN is not inherently secure; lateral movement from a compromised workstation to this server is a realistic attack path, especially if the console uses HTTP (port 8443) without encryption.

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.
