Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Nagios XI versions prior to 5.11.3 contain a SQL injection vulnerability, tracked as CVE-2023-48084 and assigned CWE-89, that resides in the bulk modification tool. The flaw carries a CVSS 3.1 base score of 9.8, reflecting network attack vector, low attack complexity, and no required privileges or user interaction, with high impact on confidentiality, integrity, and availability.

An unauthenticated remote attacker can supply crafted input through the bulk modification feature to execute arbitrary SQL commands against the underlying database. Successful exploitation grants the ability to read, modify, or delete data and potentially escalate to full control of the Nagios XI instance.

The supplied references point to the vendor’s security page for further information on updates. The associated EPSS score stands at 0.8209 with no indicated rise from a lower baseline.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly target injection flaws during coding and review so largely prevent CWE-89 introduction, yet the single broad outcome leaves residual risk from incomplete neutralization techniques or missed edge cases.

PR.AT-02 partial match
prevents

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

finds

The same secure-coding and static-analysis activities surface missing neutralization of SQL metacharacters before the system is accepted.

prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

prevents

Secure-coding rules and security testing phases mandate the use of parameterized queries or equivalent escaping, preventing the construction of dynamic SQL statements from untrusted input.

prevents

Language-specific secure coding rules, peer review and SAST together prevent the construction of SQL statements from untrusted data without proper parameterization or escaping.
