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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Jan 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-2024-57822, organizations should monitor for official patches or updates from the librdf project and apply them promptly once available. In the interim, implement strict input validation and sanitization on RDF data before parsing to prevent malformed triples from triggering the vulnerability. Restrict access to systems and services that perform RDF parsing to trusted users and networks to minimize local exploitation risk. Employ runtime protections such as memory safety tools (e.g., AddressSanitizer) during development and testing to detect out-of-bounds reads. Consider isolating RDF parsing components in sandboxed or containerized environments to limit the impact of potential crashes. Regularly audit and update dependencies to ensure usage of secure library versions. Finally, maintain robust monitoring and logging to detect unusual application crashes or denial of service symptoms related to RDF parsing.

Description

In Raptor RDF Syntax Library through 2.0.16, there is a heap-based buffer over-read when parsing triples with the nquads parser in raptor_ntriples_parse_term_internal().

Impact

For European organizations, the primary impact of CVE-2024-57822 is potential denial of service due to application crashes when processing malicious or malformed RDF data. This can disrupt services relying on semantic web technologies, linked data processing, or RDF triple stores, which are increasingly used in data integration, knowledge graphs, and AI applications. Although the vulnerability does not compromise data confidentiality or integrity, service availability interruptions can affect business operations, especially in sectors like research, government, and technology where RDF data is prevalent. The requirement for local access limits remote exploitation, reducing the risk of widespread attacks. However, insider threats or compromised internal systems could leverage this vulnerability to cause disruptions. The lack of known exploits suggests a low immediate threat, but organizations should remain vigilant given the growing adoption of RDF technologies in Europe.

CWE-125Out-of-bounds Read (opens in a new tab)
Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
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.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
