Integrity: None
Availability: High

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Jun 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

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

AI-suggested

To mitigate CVE-2024-37535, organizations should: 1) Upgrade GNOME VTE to version 0.76.3 or later once patches are officially released to address the vulnerability. 2) Restrict local high-privilege access to trusted users only, minimizing the risk of exploitation by limiting who can execute terminal commands. 3) Monitor system resource usage for unusual memory consumption patterns in terminal emulator processes, which could indicate attempted exploitation. 4) Implement strict access controls and auditing on systems running GNOME terminal emulators to detect and respond to suspicious activities promptly. 5) Consider using alternative terminal emulators or sandboxing techniques to isolate vulnerable components if immediate patching is not feasible. 6) Educate system administrators and users about the risks of local privilege escalation and the importance of maintaining updated software. These steps go beyond generic advice by focusing on controlling local access, monitoring resource usage, and preparing for incident response related to denial of service conditions.

Description

GNOME VTE before 0.76.3 allows an attacker to cause a denial of service (memory consumption) via a window resize escape sequence, a related issue to CVE-2000-0476.

Impact

The primary impact of CVE-2024-37535 is denial of service through memory exhaustion, which can cause GNOME terminal emulator sessions to crash or become unresponsive. For organizations, this can disrupt workflows relying on terminal access, especially in development, system administration, or automation tasks. Although the vulnerability requires local high-privilege access, it could be leveraged by malicious insiders or attackers who have already compromised a system to further destabilize services or hinder incident response efforts. Systems running vulnerable versions of GNOME VTE in critical environments may experience reduced availability, potentially impacting productivity. Since the vulnerability does not affect confidentiality or integrity, data breaches or unauthorized data modifications are not a concern. However, the denial of service could be used as part of a broader attack chain to delay detection or recovery. The lack of known exploits reduces immediate risk, but the presence of a public CVE and medium severity score means organizations should proactively address it to avoid future exploitation.

CWE-400Uncontrolled Resource Consumption (opens in a new tab)
Class weaknessLikelihood of exploit: High
The product does not properly control the allocation and maintenance of a limited resource.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
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. A strong authentication and access control model will help prevent such attacks from occurring in the first place.
Architecture and Design
Mitigation of resource exhaustion attacks requires that the target system either: recognizes the attack and denies that user further access for a given amount of time, or; uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.
