Exploitation

Actively exploited

High severity · No CVSS score from NVD or the CNA

KEV deadline: 15 Sep 2025 US federal agencies must patch by this date; a sensible deadline for everyone else.
EPSS: 4.3% chance of exploitation in 30 days – higher than 91% of CVEsExploit Prediction Scoring System: the likelihood attackers will use this flaw soon.
Patch: Available – fixed in 2.43.5-1.el9_4.2

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CISA KEV (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 2.43.5-1.el9_4.2.

Affected software

Product	Affected	Fixed in
Red Hat Product Security Red Hat	Affected >=2.43.5-1.el9_4.1 <2.43.5-1.el9_4.2	Fixed in 2.43.5-1.el9_4.2

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Description

Red Hat has issued a security advisory for Git addressing two vulnerabilities (CVE-2025-48384 and CVE-2025-48385) affecting Git versions distributed with Red Hat Enterprise Linux 9.4 Extended Update Support. These vulnerabilities allow arbitrary code execution and arbitrary file writes, respectively. The advisory rates the impact as Important and provides updated packages to remediate the issues.

Impact

Successful exploitation of CVE-2025-48384 could allow an attacker to execute arbitrary code, while CVE-2025-48385 could permit arbitrary file writes. Both vulnerabilities pose significant risks to system integrity and security. The impact is rated as Important by Red Hat, indicating a high severity level that could lead to compromise of affected systems if unpatched.

Mitigation

Red Hat has released updated Git packages (version 2.43.5-1.el9_4.2) that fix these vulnerabilities. Users of affected Red Hat Enterprise Linux 9.4 Extended Update Support versions should apply the provided security updates as detailed in the Red Hat advisory (https://access.redhat.com/articles/11258). No additional mitigations are indicated beyond applying the official patches.

CWE-93Improper Neutralization of CRLF Sequences ('CRLF Injection') (opens in a new tab)
Base weaknessOWASP Top 10 A05:2025: Injection (opens in a new tab)
The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.
Implementation
Avoid using CRLF as a special sequence.
Implementation
Appropriately filter or quote CRLF sequences in user-controlled input.

CWE-88Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') (opens in a new tab)
Base weaknessOWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.
Implementation · Parameterization
Where possible, avoid building a single string that contains the command and its arguments. Some languages or frameworks have functions that support specifying independent arguments, e.g. as an array, which is used to automatically perform the appropriate quoting or escaping while building the command.
Architecture and Design · Input Validation
Understand all the potential areas where untrusted inputs can enter your product: parameters or arguments, cookies, anything read from the network, environment variables, request headers as well as content, URL components, e-mail, files, databases, and any external systems that provide data to the application.
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.

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
