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 19 Apr 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

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 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.

AI-suggested

To mitigate CVE-2024-31744, organizations should implement the following specific measures: 1) Restrict or validate all JPEG-2000 image inputs to ensure they originate from trusted sources before processing with Jasper. 2) Employ input sanitization or filtering to detect and block malformed or suspicious JPEG-2000 files. 3) Monitor application logs and crash reports for signs of assertion failures or unexpected terminations related to image processing. 4) Where possible, isolate image processing components in sandboxed or containerized environments to limit the impact of crashes. 5) Consider using alternative image processing libraries that do not exhibit this vulnerability until an official patch is released. 6) Engage with the Jasper project or maintainers to track patch releases and apply updates promptly once available. 7) Implement rate limiting or other controls on image upload endpoints to reduce the risk of denial of service through repeated exploitation attempts.

Description

In Jasper 4.2.2, the jpc_streamlist_remove function in src/libjasper/jpc/jpc_dec.c:2407 has an assertion failure vulnerability, allowing attackers to cause a denial of service attack through a specific image file.

Impact

The primary impact of CVE-2024-31744 is denial of service, which can disrupt services or applications that rely on Jasper for JPEG-2000 image decoding. This can lead to application crashes, service downtime, and potential disruption of workflows in environments processing untrusted or user-supplied images. Organizations that use Jasper in web services, content management systems, or embedded devices may experience availability issues if attackers supply malicious images. While the vulnerability does not compromise data confidentiality or integrity, repeated exploitation could degrade user trust and operational stability. In critical environments such as media processing pipelines, digital forensics, or medical imaging systems, such disruptions could have significant operational consequences. The lack of authentication or user interaction requirements increases the risk of automated exploitation attempts, especially in internet-facing applications.

CWE-617Reachable Assertion (opens in a new tab)
Base weakness
The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.
Implementation
Make sensitive open/close operation non reachable by directly user-controlled data (e.g. open/close resources)
Implementation · Input Validation
Perform input validation on user data.
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
