inferred from weakness class no curated mapping exists for this CVE; these are the techniques typically seen with CWE-252, CWE-787 vulnerabilities
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Inferred from CWE-787.
Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries.
Inferred from CWE-787.
Adversaries may exploit software vulnerabilities in client applications to execute code.
Inferred from CWE-787.
An adversary may rely upon specific actions by a user in order to gain execution.
via sub-technique T1204.002 Malicious File
Inferred from CWE-787.
Adversaries may execute their own malicious payloads by hijacking the way operating systems run programs.
Inferred from CWE-787.
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Inferred from CWE-787.
A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream. Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1.
CVSS measures how bad exploitation would be; EPSS estimates how likely exploitation is within 30 days; the CISA listing means it is already happening. Read them together: a CVSS 9.8 with EPSS 0.04% is usually less urgent than a CVSS 7.2 on the exploited list. Data: NVD, FIRST EPSS, CISA KEV; detail is cached for a week, scores for a day. ATT&CK techniques come from the CTID KEV mappings project where a curated mapping exists, otherwise they are inferred from the weakness class and labelled as such.
