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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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 20 Mar 2025
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

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.

AI-suggested

To mitigate CVE-2024-10935, organizations should implement the following specific measures: 1) Apply any available patches or updates from the automatic1111 project as soon as they are released. 2) If patches are unavailable, deploy web application firewalls (WAFs) or reverse proxies configured to detect and block malformed multipart requests with suspiciously long or malformed boundary strings. 3) Implement strict input validation on multipart boundaries, enforcing maximum length limits and rejecting requests exceeding these thresholds. 4) Introduce resource throttling and rate limiting on multipart/form-data parsing to prevent excessive memory or CPU consumption from malformed requests. 5) Monitor server resource usage and network traffic for unusual spikes indicative of attempted DoS attacks targeting multipart boundaries. 6) Restrict access to stable-diffusion-webui instances to trusted networks or authenticated users where possible to reduce exposure. 7) Conduct regular security assessments and penetration testing focusing on multipart request handling. 8) Educate development and operations teams about CWE-770 risks and secure coding practices related to resource allocation. These targeted mitigations go beyond generic advice by focusing on multipart boundary handling and resource management specific to this vulnerability.

Description

automatic1111/stable-diffusion-webui version 1.10.0 contains a vulnerability where the server fails to handle excessive characters appended to the end of multipart boundaries. This flaw can be exploited by sending malformed multipart requests with arbitrary characters at the end of the boundary, leading to excessive resource consumption and a complete denial of service (DoS) for all users. The vulnerability is unauthenticated, meaning no user login or interaction is required for an attacker to exploit this issue.

Impact

For European organizations, the impact of CVE-2024-10935 can be significant, particularly for those relying on automatic1111/stable-diffusion-webui for AI image generation workflows, research, or creative projects. A successful exploitation leads to a denial of service, causing service outages and disruption of operations. This can affect productivity, delay projects, and potentially lead to financial losses. Since the vulnerability is unauthenticated and remotely exploitable, attackers can launch DoS attacks without insider access, increasing the attack surface. Critical sectors such as research institutions, media companies, and AI startups using this tool may experience downtime, impacting their service availability and reputation. Additionally, organizations hosting public-facing instances of this web UI are at higher risk of external DoS attacks. The lack of confidentiality or integrity impact means data breaches or tampering are not a direct concern, but availability degradation alone can have cascading effects on dependent systems and users. The absence of known exploits currently provides a window for proactive mitigation before widespread attacks occur.

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.
