Vulnerability from variot - Updated: 2023-12-18 11:25

AVEVA System Platform versions 2017 through 2020 R2 P01 uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. AVEVA Provided by the company AVEVA System Platform The following multiple vulnerabilities exist in. * Lack of authentication for important features (CWE-306) - CVE-2021-33008 ‥ * Problems not handling exceptions (CWE-248) - CVE-2021-33010 ‥ * Path traversal (CWE-22) - CVE-2021-32981 ‥ * Same-origin policy violation (CWE-346) - CVE-2021-32985 ‥ * Improper verification of digital signatures (CWE-347) - CVE-2021-32977The expected impact depends on each vulnerability, but it may be affected as follows. * Arbitrary code execution with system privileges by a third party on the adjacent network - CVE-2021-33008 ‥ * Service operation obstruction by a remote third party (DoS) Be in a state - CVE-2021-33010 ‥ * The input value that specifies a file or directory under the access-restricted directory is not properly processed, so it is accessed outside the access-restricted directory by a remote third party. - CVE-2021-32981 ‥ * Do not properly verify that the data or source is valid - CVE-2021-32985 ‥ * Do not verify or incorrectly verify the digital signature of the data - CVE-2021-32977.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
