CVE-2021-45460 (GCVE-0-2021-45460)

Vulnerability from cvelistv5 – Published: 2022-01-11 11:27 – Updated: 2024-08-04 04:39
VLAI
Summary
A vulnerability has been identified in SICAM PQ Analyzer (All versions < V3.18). A service is started by an unquoted registry entry. As there are spaces in this path, attackers with write privilege to those directories might be able to plant executables that will run in place of the legitimate process. Attackers might achieve persistence on the system ("backdoors") or cause a denial of service.

Mitigation
Implementation

Properly quote the full search path before executing a program on the system.

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
Mitigation MIT-20
Implementation

Strategy: Input Validation

Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
