VAR-200610-0259
Vulnerability from variot - Updated: 2025-04-10 23:13XORP (eXtensible Open Router Platform) 1.2 and 1.3 allows remote attackers to cause a denial of service (application crash) via an Open Shortest Path First (OSPF) Link State Advertisement (LSA) with an invalid LSA length field. Exploiting this issue allows remote, unauthenticated attackers to crash the application, denying further service to legitimate users. eXtensible Open Router Platform versions 1.2 and 1.3 are vulnerable to this issue.

TITLE: XORP OSPF Link State Advertisements Denial of Service
SECUNIA ADVISORY ID: SA22462
VERIFY ADVISORY: http://secunia.com/advisories/22462/
CRITICAL: Moderately critical
IMPACT: DoS
WHERE:
From remote
SOFTWARE: XORP 1.x http://secunia.com/product/12372/
DESCRIPTION: Mu Security has reported a vulnerability in XORP, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an out of bounds read when processing Link State Advertisements (LSA). This can be exploited to crash the OSPF daemon by sending LSAs with invalid length values.
The vulnerability is reported in XORP 1.2 and 1.3. Other versions may also be affected.
SOLUTION: Follow vendor instructions to apply patches.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
