Vulnerability Data

A directory traversal vulnerability exists in Ivanti LANDesk Management Gateway through 4.2-1.9. By appending %3F.php to the URI of the /client/index.php endpoint, an attacker can bypass access controls and gain unauthorized access to various endpoints such as /client/index.php%3F.php/gsb/firewall.php within the…

management web panel, potentially exposing sensitive device information. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

SA-11 requires developer testing and evaluation that can discover validation-order defects after they have been coded.

SI-10 Information Input Validation good match

SI-10 requires validity checks on inputs; when implemented with canonicalization preceding validation it structurally prevents the exact ordering flaw.

SA-8 Security and Privacy Engineering Principles partial match

SA-8 mandates security engineering principles that include correct canonicalization-before-validation ordering for input handling.

PR.PS-06 mostly match

prevents

Secure SDLC practices directly require correct validation order after canonicalization to prevent bypasses.

A.8.29 Security testing in development and acceptance mostly match

finds

Security testing can detect validation-order defects before deployment.

A.8.25 Secure development life cycle partial match

prevents

Secure SDLC mandates input validation and canonicalization order, directly addressing CWE-180.

A.8.26 Application security requirements partial match

prevents

Application security requirements include proper input handling to prevent validation-before-canonicalization flaws.

A.8.27 Secure system architecture and engineering principles partial match

prevents

Secure architecture principles reduce the likelihood of ordering errors in input processing.

A.8.28 Secure coding partial match

prevents

Secure coding standards explicitly require canonicalize-then-validate to eliminate CWE-180.
