Exploitation evidence

Disclosed: evidence found.
CVE published 12 Dec 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Red Hat to 3.12.8.

AI-suggested

Red Hat has released updated python3.12 packages for Red Hat Enterprise Linux 8 that fix these vulnerabilities. Users should apply the python3.12 update (version 3.12.8-1.el8_10) available from Red Hat to remediate these issues. For detailed update instructions, refer to the Red Hat article at https://access.redhat.com/articles/11258. No additional mitigations are indicated by the vendor advisory.

Description

Red Hat has issued a security advisory for python3.12 addressing two vulnerabilities: CVE-2024-9287, where virtual environment activation scripts do not quote paths, and CVE-2024-12254, involving unbounded memory buffering in SelectorSocketTransport.writelines(). These issues affect Red Hat Enterprise Linux 8 and related variants. The advisory rates the update as important and provides updated packages to remediate these vulnerabilities.

Impact

The vulnerabilities could allow attackers to exploit improper path quoting in venv activation scripts or cause unbounded memory consumption in socket transport operations, potentially leading to denial of service or other impacts related to resource exhaustion. The advisory classifies the security impact as Important (high severity). There are no known exploits in the wild at the time of the advisory.

CWE-428Unquoted Search Path or Element (opens in a new tab)
Base weakness
The product uses a search path that contains an unquoted element, in which the element contains whitespace or other separators. This can cause the product to access resources in a parent path.
Implementation
Properly quote the full search path before executing a program on the system.
Implementation · 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.
Implementation · 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).
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
